This framework begins with the portfolio's job rather than with products, managers, or return forecasts. Trustees first map required benefit payments, contribution streams, investment income, time horizons, and liquidity needs. They then select a diversified asset allocation capable of meeting those obligations across current and future periods. Low-cost index funds provide the default implementation because persistent net-of-fee outperformance is difficult, especially at very large scale. Active or private investments must earn their place through a specific source of diversification, cash flow, or illiquidity premium—not merely through infrequent valuation marks. Contribution smoothing and other funding mechanics can address short-term volatility separately. The resulting portfolio is judged by its ability to fund liabilities efficiently, not by the prestige or number of its managers.
Origin
Warshaw presented this approach on Masters in Business while arguing that New York's pension fund should replace hundreds of active managers with diversified low-cost index exposure.
Core principles
- 01A fund's obligations should determine its portfolio design.
- 02Asset allocation drives most portfolio outcomes.
- 03Diversification is not the same as hiring many managers.
- 04Fees must be justified by net-of-fee performance.
- 05Private ownership does not eliminate underlying economic risk.
- 06Volatility management and investment selection are separate problems.
How to run it
- 1
Write the fund's job description
Specify the benefits the fund must pay, when they are due, and how long the institution is expected to operate.
Pro tip Model both current payouts and obligations several decades into the future.
Watch out Do not begin with available investment products or expected returns.
- 2
Map incoming cash
Quantify contributions, investment income, and other dependable inflows under multiple economic conditions.
Pro tip Separate legally required contributions from less dependable assumptions.
Watch out Strong funding rules can conceal weak investment performance by shifting costs to contributors.
- 3
Set the liquidity floor
Determine how much of the portfolio must remain liquid to meet foreseeable payouts and contingencies.
Pro tip Use multiple liquid asset classes rather than assuming the entire portfolio must be immediately tradable.
Watch out Do not lock up assets merely because the fund has a long horizon.
- 4
Allocate across economic risks
Construct a diversified mix of assets whose return and cash-flow characteristics fit the fund's obligations.
Pro tip Evaluate diversification by underlying economic exposure, not by ownership labels.
Watch out Private ownership can hide reported volatility without changing the asset's economic sensitivity.
- 5
Default to low-cost implementation
Use diversified index funds where active selection lacks a credible and measurable net-of-fee advantage.
Pro tip Compare every active mandate with the cheapest investable benchmark serving the same role.
Watch out Hiring many active managers can create an expensive index with poor tracking.
- 6
Make exceptions prove themselves
Require active and private allocations to demonstrate a specific source of alpha, diversification, cash flow, or compensated illiquidity.
Pro tip State the expected benefit and invalidation condition before committing capital.
Watch out Do not treat stale valuations as evidence of low risk.
- 7
Review outcomes against the job
Measure funding progress, liquidity, net returns, fees, and risk relative to the obligations defined at the start.
Pro tip Review funding mechanics separately from investment-manager performance.
Watch out A fully funded status alone does not show whether investments performed efficiently.
In the wild
A large pension fund pays hundreds of managers but trails its own benchmarks after fees. Trustees map annual benefits and contributions, establish a liquidity reserve, and replace overlapping mandates with diversified low-cost indexes while retaining only clearly differentiated exposures.
→ The fund lowers fees, improves transparency, and aligns implementation with its benefit obligations.
A pension committee considers private credit because its reported returns appear less volatile. Under the framework, the committee examines the underlying borrower risks, lockup, fees, expected cash flows, and whether the allocation adds genuine diversification beyond public credit.
→ The committee approves only the portion supported by a compensated illiquidity premium rather than accounting smoothness.
Common mistakes
Starting with managers
Selecting managers before defining obligations lets products drive strategy instead of serving it.
Confusing stale prices with low risk
Infrequent private-market valuations can suppress reported volatility without reducing underlying economic exposure.
Judging only by funded status
Mandatory taxpayer or employer contributions may keep a pension funded even when investment performance is inefficient.
Is it for you?
Best for
It is best for pension funds, endowments, and other long-horizon institutions with predictable obligations.
Not ideal for
It is not designed for individuals with short horizons, unstable cash needs, or concentrated personal liabilities.
