One winner can carry the fund
A fund's return can change sharply with ownership, dilution, exit timing and sale price. A company may grow a great deal yet fail to return the fund. The manager may own too little at exit, or buyers may pay a lower multiple than expected. Sensitivity analysis shows which assumptions matter most.
Sensitivity analysis identifies which assumptions must remain true for the investment case to work, then shows what happens when two of them weaken together. It makes the dependencies visible. It does not make the forecast more accurate.
CalPERS' 2026 Private Equity Annual Program Review illustrates why dispersion matters at the total-fund level. Venture outcomes are uneven, so changes in a few large positions can move the whole portfolio. Rebuilding the base case reveals those dependencies.
The gross result changes again before reaching the LP. Under a common 20% carry structure, a concentrated gross gain can produce a much smaller net result.
Exit value and dilution interact; an attractive headline exit can still produce a modest ownership-level return. Illustrative gross ownership-level MOIC before fees, carry, taxes, and timing effects; calculated as exit multiple multiplied by retained ownership.

| Review area | 1.5x exit | 2x exit | 3x exit | 4x exit | 6x exit |
|---|---|---|---|---|---|
| 0% dilution | 1.5x | 2x | 3x | 4x | 6x |
| 20% dilution | 1.2x | 1.6x | 2.4x | 3.2x | 4.8x |
| 40% dilution | 0.9x | 1.2x | 1.8x | 2.4x | 3.6x |
| 60% dilution | 0.6x | 0.8x | 1.2x | 1.6x | 2.4x |
Ownership can matter as much as the exit
A 2% stake in a company exiting for $5 billion produces $100 million of gross proceeds. If the fund owns 1% at exit, the same company and the same sale produce only $50 million.
The difference is large enough to change the fund's return. A model may carefully defend a $5 billion exit while assuming ownership stays constant. Future rounds and option-pool increases can reduce the stake, weakening the result even if that exit value is reached.
A 25% dilution event reduces a 2% stake to 1.5%. At the same $5 billion exit, gross proceeds fall from $100 million to $75 million. The company still succeeds; the fund simply captures less of that success.
The Rest of the Portfolio Changes the Winner's Burden
In a 20-company equal-cost portfolio, one 10x investment contributes 0.5x to fund value. A 20x investment contributes 1.0x. The other 19 positions still determine whether the fund returns capital or turns that winner into an attractive overall multiple.
This is where the loss ratio and reserve plan meet. More failures increase the burden on the leaders. Poorly directed follow-ons add cost without preserving meaningful ownership. Changes in the winner and the rest of the portfolio therefore interact.
A Few Cases Can Reveal the Main Risks
A compact model can show how time changes annualized return, how dilution reduces a winner's impact and how a more cautious mark changes NAV. Consistent assumptions make those cases comparable.
| Case | What Changes | LP Question |
|---|---|---|
| Base | Manager's stated ownership, timing, and exit assumptions. | Is the case internally consistent? |
| Delay | Same exit value, but liquidity arrives three years later. | Does IRR still fit the LP objective? |
| Dilution | Ownership declines through follow-on financings. | Does the winner still move the fund? |
| Mark-down | Largest unrealized positions are reduced significantly. | How dependent is performance on current NAV? |
How the Result Reaches the LP
Carta reports a median 2% management fee and 20% carry. Company proceeds first contribute to gross fund value. The fund's fees and carry then reduce the cash that reaches the LP, so a strong company outcome can become a more modest investor return.
Timing belongs in the same bridge. Moving an exit three years later leaves the multiple unchanged but lowers IRR. A discounted secondary can reduce both. Fees, expenses, and carry then determine how much of the remaining value reaches the investor.
What the Sensitivity Table Reveals
The largest movements in the table reveal which parts of the investment case carry the most weight. When retained ownership drives the result, follow-on plans and dilution explain much of the risk. A model dependent on today's marks rests on the evidence behind those values. When a delay causes the largest change, the distribution schedule matters more to the LP's cash plan.
Evidence for the variables that move the result gives the LP a firmer basis for confidence. An unsupported assumption creates a weaker case. The table shows where more diligence could help while leaving the future uncertain.
The portfolio plan sets much of the range in the sensitivity cases. Company count and cheque size shape initial exposure. Ownership and reserves change the stakes over time, determining how much a large winner can contribute.
Klarna: Company Progress and Valuation Can Move in Opposite Directions
Klarna offers a useful reminder that operating progress and investment value do not move in lockstep. In July 2022, the company raised $800 million of common equity at a $6.7 billion post-money valuation during a severe public-market downturn. It also noted that this value remained three times its 2018 level.
Klarna intended the financing primarily to support its US expansion.
The new price nevertheless represented a sharp reset from the prior private-market peak.
Klarna also reported roughly 2 million transactions a day. Investors could weigh that scale against the lower price.
Operating growth and valuation multiples can move in opposite directions. A company may add users and strategic value while a market reset lowers the price investors will pay.

Frequently Asked Questions
Which variables matter most in a venture fund sensitivity analysis?
Exit value, timing and retained ownership directly affect proceeds. Reserves and losses change the portfolio around them, while fees, expenses and carry reduce what reaches LPs. Sensitivity analysis reveals which of these changes moves the result most.
Is a sensitivity analysis a return forecast?
A sensitivity analysis is a decision tool that shows how outcomes change when key assumptions move. It helps the LP understand what drives the case without claiming to predict which scenario will occur.
