The gate evaluates private-equity suitability through three practical questions: whether the investor has a sufficiently long horizon, whether cash flows indicate accumulation rather than substantial decumulation, and whether a fiduciary can manage allocation and rebalancing within a complete portfolio. Wealth and income thresholds may establish regulatory eligibility, but they do not prove that an investor can tolerate illiquidity. A wealthy client spending rapidly may face greater forced-sale risk than a moderate-income retirement saver with decades before withdrawals. The framework therefore projects spending, reserves, capital calls, and adverse scenarios before approving an allocation. Professional management strengthens suitability because the fiduciary can size the exposure, coordinate liquidity, and reduce it before the investor begins drawing retirement income.
Origin
Extracted from Masters in Business, where Fran Kinniry argued that prudence should depend on horizon and professional management rather than wealth alone.
Core principles
- 01Wealth does not guarantee liquidity capacity
- 02Investment horizon matters more than eligibility alone
- 03Accumulation supports illiquid commitments better than heavy decumulation
- 04Professional portfolio management can control allocation and rebalancing
- 05High spending can make even wealthy investors unsuitable
How to run it
- 1
Establish the Lock-Up Horizon
Determine how long capital may remain inaccessible and when distributions could realistically occur. Compare that schedule with the investor’s known obligations.
Pro tip Use a conservative distribution schedule rather than the manager’s optimistic case.
Watch out Nominal eligibility does not make a short-horizon investor suitable.
- 2
Map Cash Flows
Project income, spending, emergency reserves, taxes, capital calls, and major planned purchases. Identify whether the investor is accumulating assets or drawing them down.
Pro tip Separate recurring spending from discretionary spending that could be reduced.
Watch out High spending can overwhelm even a large portfolio.
- 3
Stress-Test Liquidity
Model delayed distributions, market losses, and unexpected expenses occurring together. Measure whether liquid assets can cover needs without selling private holdings.
Pro tip Include a scenario in which secondary-market discounts widen during stress.
Watch out Assuming stable secondary-market liquidity understates forced-sale risk.
- 4
Assess Governance
Confirm who will size the allocation, handle capital calls, rebalance the broader portfolio, and monitor changing circumstances. Prefer fiduciary oversight within a multi-asset plan.
Pro tip Assign responsibility for every operational decision before committing.
Watch out Self-directed ownership can fail when no one coordinates liquidity and rebalancing.
- 5
Approve or Reject
Approve private equity only when horizon, cash flow, stress capacity, and governance all support it. Otherwise reduce the proposed allocation or reject it.
Pro tip Document why the investor is suitable, not merely why the product is attractive.
Watch out Do not let expected returns override a failed liquidity test.
In the wild
A client owns $15 million but spends $2 million to $3 million annually and may need additional cash for lifestyle commitments. Although the client clears wealth and income thresholds, the adviser rejects private equity because rapid decumulation creates forced-sale risk.
→ The suitability decision protects liquidity despite the client’s formal eligibility.
A worker has decades before retirement, contributes regularly, maintains an emergency reserve, and receives portfolio management through a diversified retirement vehicle. A modest private allocation is approved with a plan to stop new commitments before retirement.
→ The allocation matches the investor’s accumulation phase and long horizon.
Common mistakes
Equating Wealth with Capacity
Large assets do not offset an unsustainable spending rate or imminent liquidity needs.
Ignoring the Spending Phase
An investor drawing down assets has a different capacity for illiquidity than one making steady contributions.
Assuming Liquidity Will Appear
Secondary markets may exist, but stressed sales can require significant discounts.
Is it for you?
Best for
It is best for advisers and fiduciaries evaluating whether an investor can responsibly hold illiquid assets.
Not ideal for
It is not ideal as a substitute for legal, tax, operational, or manager-level due diligence.
From the transcript
“I really think it's it's much more appropriate to think about what is the horizon of the investor”
“when it is professionally managed and it meets the time horizon and the investor is in accumulation or slight accumulation, that's where I would put…”
“the real gates of prudence as opposed to just wealth and income.”
