Economic Balance Sheet and Liability-Relative Asset Allocation

Updated 9 October 2026 · Fact-checked

An economic balance sheet lists all of an investor's assets and liabilities, including non-financial ones such as human capital and pension obligations, at present value. Economic net worth is the difference. A liability-relative approach sets the allocation to fund or hedge those liabilities, instead of only maximising portfolio return for a given risk.

Understand Economic Balance Sheet and Liability-Relative Allocation

A normal balance sheet shows only financial items. An economic balance sheet is wider. It adds items that are not on the accounting statements but still matter to the investor's ability to meet goals. Think of the whole picture, not just the portfolio.

On the asset side you include financial assets, and also human capital (the present value of future earnings for an individual), the present value of expected pension or social benefits, and for an institution, items such as the present value of expected future contributions from a sponsor or donors. On the liability side you include debts and also the present value of future spending needs, such as living expenses, taxes, bequests, or promised benefits to plan members.

Economic net worth = economic assets − economic liabilities. It is the investor's real surplus (or deficit) once all claims are counted. Two investors with the same financial portfolio can have very different economic net worth and so very different capacity for risk.

The balance sheet also shows risk exposure. Human capital behaves like a bond if earnings are stable (a tenured professor), and like equity if earnings are tied to markets or the business cycle (an investment banker). A stable earner can often hold more risky financial assets. A cyclical earner may need to hold safer financial assets to diversify total wealth.

This leads to the two approaches. An asset-only approach picks the allocation by looking at asset returns, risks and correlations, with liabilities considered only as a constraint. A liability-relative approach builds the allocation around the liabilities: it asks how well assets will fund them, and focuses on the funding ratio or surplus and its volatility. Liability-relative suits investors with defined, large, dated obligations such as defined benefit plans and insurers. A goals-based approach, a third method, splits the portfolio by goals. This page focuses on the first two.

Key rules to remember

Economic net worth: Economic net worth = PV(economic assets) − PV(economic liabilities); Economic assets include financial assets, human capital and the PV of expected benefits. Liabilities include debts and the PV of future spending or promised benefits.
Funding ratio: Funding ratio = PV of assets ÷ PV of liabilities; Above 1 is a surplus, below 1 is a deficit. Liability-relative investors manage this ratio or the surplus.
Surplus: Surplus = Assets − Liabilities; Liability-relative risk is often the volatility of the surplus, not of assets alone.
Surplus return (approximate): Surplus return ≈ (ΔA − ΔL) ÷ A = (Asset return × A − Liability return × L) ÷ A, where A = beginning assets, L = beginning liabilities, ΔA = change in assets and ΔL = change in liabilities; The base is beginning assets A: surplus return is the change in surplus divided by beginning assets. Asset return is the percentage change in asset value. Liability return is the percentage change in the PV of the liabilities. It is negative when rates rise, because the PV falls, and positive when rates fall, because the PV rises. So a fall in rates raises the PV of liabilities and can hurt the surplus even when assets rise.
Asset-only vs liability-relative: Asset-only: choose assets by return, risk, correlation. Liability-relative: choose assets to fund or hedge the liability.; Liability-relative is the better fit when liabilities are large, fixed and dated.

How to solve Economic Balance Sheet and Liability-Relative Allocation questions

Use the same sequence for any question on the economic balance sheet or the choice of approach. Tie each step to the client's objectives and constraints.

1Identify the investor type and the objective: wealth growth, meeting a spending need, or paying promised benefits.
2List all assets, including non-financial ones such as human capital and the PV of expected benefits. Put every item at present value.
3List all liabilities, including future spending, taxes, bequests or promised benefits, at present value.
4Compute economic net worth (assets − liabilities) or the funding ratio, and note any deficit or surplus.
5Judge the nature of the non-financial items: bond-like (stable) or equity-like (cyclical). Decide how they change the risk the financial portfolio can carry.
6Pick the approach: asset-only for flexible or weak liabilities, liability-relative for large, fixed, dated liabilities.
7State the allocation implication in one sentence, linked to ability and willingness to take risk.
8Check the question wording and answer only what the command word asks for.

Quickest way: Three-line balance sheet check

When to use it: Use when time is short and the question gives a few numbers and asks for net worth, funding status or the better approach.

Write A (all assets at PV) and L (all liabilities at PV). Subtract to get net worth or divide for the funding ratio.
Ask: are the liabilities large, fixed and dated? If yes, choose liability-relative. If no, asset-only is acceptable.
Ask: is human capital stable (bond-like) or cyclical (equity-like)? Stable supports more risk in the portfolio. Cyclical supports less.

Common mistakes in Economic Balance Sheet and Liability-Relative Allocation

Counting only the financial portfolio as the investor's assets.
Accounting statements show only financial items, so students copy that habit.
Fix: Always scan for human capital, expected pension or social benefits, and expected sponsor contributions. Include them at present value.
Mixing present values with future values or undiscounted amounts.
Vignettes list future spending needs and future earnings in nominal amounts.
Fix: Discount every future item at an appropriate rate before you subtract. Do not net a future figure against a present one.
Treating all human capital as low risk.
Students remember the bond-like example and apply it everywhere.
Fix: Judge each case: stable, secure income is bond-like. Income tied to markets or business cycles is equity-like and correlates with the portfolio.
Calling an approach liability-relative just because liabilities are mentioned.
Every approach mentions liabilities somewhere.
Fix: Liability-relative sets the allocation by how assets fund or hedge the liabilities and focuses on surplus or funding ratio. Asset-only uses liabilities only as a constraint.
Ignoring the sign and base when computing surplus risk.
Students look only at asset volatility.
Fix: Remember that the liability moves too. Rising assets with an even larger rise in the PV of liabilities (for example when rates fall) reduces the funding ratio.
Giving a long discussion when the command word is 'calculate' or 'identify'.
Students want to show full knowledge.
Fix: Answer the command word exactly. Show the calculation for 'calculate' and give a short reason only when asked to justify.

Worked examples

Example 1

An investor has financial assets of ₹80,00,000. The present value of her expected future earnings (human capital) is ₹1,20,00,000. The present value of her expected future living expenses and other spending is ₹1,35,00,000 and she has a home loan of ₹25,00,000. Calculate her economic net worth and state what it shows.

Show the solution

Economic assets = 80,00,000 + 1,20,00,000 = ₹2,00,00,000.
Economic liabilities = 1,35,00,000 + 25,00,000 = ₹1,60,00,000.
Economic net worth = 2,00,00,000 − 1,60,00,000 = ₹40,00,000.
Interpretation: all claims are covered with a positive surplus, so the plan is funded on an economic basis.

Answer: Economic net worth is ₹40,00,000. It is positive, so her assets, including human capital, cover all her liabilities. Most of her wealth sits in human capital, so the stability of her income affects how much risk her financial portfolio can carry.

Example 2

A defined benefit plan has assets with a present value of $540 million and liabilities with a present value of $600 million. The sponsor asks whether to pick the allocation by maximising expected return for a given asset volatility, or to build it around the liabilities. Calculate the funding ratio and recommend an approach.

Show the solution

Funding ratio = 540 ÷ 600 = 0.90.
Surplus = 540 − 600 = −$60 million, a deficit of $60 million.
The liabilities are large, fixed and dated (promised benefits), and the plan is underfunded.
Asset-only ignores how the liabilities move, for example when discount rates fall and their PV rises.
A liability-relative approach targets the funding ratio and surplus volatility, and can use assets that hedge the liability's interest rate sensitivity.

Answer: Funding ratio is 0.90, a deficit of $60 million. Recommend a liability-relative approach, because the obligations are large, fixed and dated and the plan must manage the surplus, not asset returns alone.

Exam tips

Read the vignette for hidden economic assets and liabilities such as pensions, future earnings and bequests, and include each at present value.
When asked to justify an approach, name the liability features (size, certainty, timing) in one sentence. That earns the points.
Link human capital to risk: say whether it is bond-like or equity-like, then state the effect on the portfolio's risk capacity.
Show your net worth or funding ratio calculation in the answer space. Type the number alone only if the question asks for a single value.
Answer only the number of responses asked for, in the order requested, as extra answers are not evaluated.

Economic Balance Sheet and Liability-Relative Allocation: frequently asked questions

What is economic net worth in asset allocation?

It is the present value of all economic assets minus the present value of all economic liabilities. Economic assets include human capital and expected benefits, not only the financial portfolio. It shows the investor's true surplus or deficit.

What is the difference between asset-only and liability-relative approaches?

Asset-only chooses the allocation from asset returns, risks and correlations, treating liabilities as a constraint. Liability-relative designs the allocation around funding or hedging the liabilities and tracks the surplus or funding ratio. The second suits large, fixed, dated obligations.

Why is human capital part of the economic balance sheet?

For many individuals it is the largest asset, and it shapes how much risk the financial portfolio can carry. Stable income acts like a bond. Cyclical income acts like equity and may call for a safer portfolio.

Which investors use a liability-relative approach?

Investors with defined, large and dated obligations, such as defined benefit pension plans and insurers, usually use it. Individuals with fixed future spending needs may also use it in part.
