You can't save bread. You can't stockpile electricity for the year 2047. You can't put next decade's healthcare in a warehouse.
Everything you will consume in retirement — every meal, every utility bill, every doctor's visit — will be produced by someone (or something) else, in the future. No amount of saving changes this. What saving does is create an arrangement that connects your current resources to your ability to buy real things later. The money is just the mechanism. What matters is the arrangement itself — whether it will actually deliver purchasing power when you need it, decades from now.
That arrangement is what we call a claim.
A claim is your bridge between resources you set aside today and the real goods and services you'll need in the future.
Every pension is a claim. Every annuity is a claim. Every 401(k) balance, every Social Security check, every tontine share — each is a different kind of bridge, built differently, maintained differently, and vulnerable to different things. But they are all, fundamentally, claims on future output — arrangements that entitle you to take some share of what the economy produces later.
Some claims are simple. A TIPS ladder is a direct claim on inflation-adjusted government payments — you own it, you control it, and its terms are spelled out. Other claims are complex. A traditional annuity routes your money through an insurer's general account, where it mixes with other obligations, gets invested across asset classes, and depends on the company's solvency, judgment, and honesty to deliver what was promised. Same goal — income you can't outlive. Completely different structure underneath.
The structure is what matters. Labels like "guaranteed" or "protected" or "lifetime income" tell you what something is called. The structure of the claim tells you what it actually does — how risk is shared, how it adjusts, whether you can access your capital, and how costs are charged.
If a claim is a bridge, you want to know whether the bridge is sound. The Longevity Standard framework characterizes every lifetime income arrangement through four structural properties — four questions that apply to any claim, no matter what it's called or how it's marketed.
Risk sharing — Who bears longevity and investment risk? Is the individual absorbing it alone, sharing it across a pool of participants, transferring it to an insurer, or some combination? This is the most consequential of the four properties because it determines where the structural value of the claim comes from. Pooling and transfer create value by spreading risk across many outcomes; individual drawdown bears the full cost of uncertainty.
Adjustment mechanism — What changes when conditions change? Does the payout respond automatically to realized experience (like a direct pool or an inflation-indexed bond), stay fixed by contract (like a SPIA), or adjust only at someone's discretion (like a cash balance plan under certain designs)? A claim that can't adjust is either overbuilt or fragile. The question is which.
Liquidity — Can the participant access their capital? Some claims preserve full access — a brokerage account or a bond ladder. Some allow partial access under specific conditions — certain pool designs permit withdrawal with a haircut. Some lock capital entirely — a SPIA converts capital to income irrevocably. Liquidity isn't just about flexibility; it's about whether you can change course if your situation changes.
Cost structure — How is the arrangement paid for? Some claims have explicit fees charged directly and disclosed openly. Some have embedded spreads — the difference between what an asset earns and what the participant is credited, invisible unless you go looking for it. Some have crediting parameters that limit upside in ways that function as costs without being called costs. Some have guarantee charges built into pricing rather than itemized. How you pay for something often determines whether you notice it at all.
If you understand these four properties, you can compare almost anything on a common footing — a government pension and a variable annuity, a tontine and a managed payout fund, a cash balance plan and a TIPS ladder — without getting trapped in marketing language or category debates.
Of the four properties, risk sharing is the most consequential. When risk is shared or transferred rather than borne individually, the natural next question is where. Who or what is actually standing behind the claim? Understanding this requires a sub-analysis — looking at what's sometimes called the backing of the claim.
There are really three possibilities.
Transfer-backed — Your future income is funded by other people contributing at the time you receive it. Social Security is the clearest example: today's workers pay today's retirees. The strength of the claim depends on the ongoing willingness and ability of contributors to keep contributing. The bridge is rebuilt in real time, every pay period.
Asset-backed — Your future income is funded by a pool of assets that have been set aside and are managed by an intermediary — an insurer, a pension fund, a trust. The strength of the claim depends on the quality of those assets, the competence and integrity of the manager, and the solvency of the institution. The bridge was built in advance, but someone else is maintaining it.
Ownership-based — Your future income comes from assets you own and control directly. A brokerage account, a bond ladder, rental property. The strength of the claim depends on your own decisions and on market outcomes. You built the bridge and you're maintaining it yourself.
Every real-world lifetime income arrangement is one of these three or a blend. A cash balance pension is asset-backed with transfer elements. A tontine is asset-backed but with ownership-like transparency. A SPIA is asset-backed and depends on the insurer's general account and the state guaranty fund as the ultimate backstop. Understanding which type of backing stands behind your claim — and what that backing depends on — is the most important thing you can know once you understand how risk is being shared in the first place.
Consider two options both described as "lifetime income."
One pays a fixed amount tied to an asset pool managed by an insurer, with embedded spreads and capital reserves that determine both the payout and the cost. The other pays a floating amount that adjusts automatically with pool experience — designed to stay solvent by sharing outcomes across participants rather than guaranteeing them.
Same label. Completely different structure. Different risk sharing (transferred in one case, directly shared in the other). Different adjustment mechanism (fixed contractual in one, automatic actuarial in the other). Different cost structure (embedded spread in one, none in the other). Different liquidity implications depending on how each is designed.
That gap — between what something is called and what it actually does — is where most lifetime income misunderstandings live. The claims lens closes that gap. It replaces labels with structure, and structure you can examine.
Every post on this site is, in one way or another, an application of this framework to a different arrangement, question, or failure mode. The four structural properties — risk sharing, adjustment mechanism, liquidity, and cost structure — give you a common language for evaluating any lifetime income claim. The three backing types give you a sub-vocabulary for understanding where the risk transfer actually lands when risk is shared or transferred rather than borne individually.
Whether it's a product on the market today, a policy proposal, or something that hasn't been built yet — the claims lens gives you a way to look at it that doesn't depend on what it's called.
