A concentration test any investor can run from the schedule of investments in ten minutes, and what it says about the NAV the fund reports.
Remove the largest position from the schedule of investments and recompute cost and fair value for what is left. In an illustrative seven-company portfolio carried at 1.37x, the largest holding is 39.2 per cent of fair value, and without it the other six are at 0.96x: below cost. One investment carries 110.1 per cent of the fund's unrealised gain.

The headline multiple in a quarterly report is an average, and in private equity averages are dominated by their largest term. The schedule of investments, the position-by-position list of cost and fair value in the audited statements, holds everything needed to test that. It takes ten minutes, needs no access to the manager's valuation files, and tells you how much of the NAV you are relying on one valuation for.
| Company | Cost | Fair value | Multiple |
|---|---|---|---|
| Brightline Software | 15,000 | 60,600 | 4.04x |
| Calder Foods | 20,000 | 24,000 | 1.20x |
| Norvale Logistics | 18,000 | 19,800 | 1.10x |
| Pellham Engineering | 22,000 | 17,600 | 0.80x |
| Quayside Clinics | 12,000 | 13,200 | 1.10x |
| Redmere Packaging | 16,000 | 15,200 | 0.95x |
| Thornfield Retail | 10,000 | 4,000 | 0.40x |
| Total | 113,000 | 154,400 | 1.37x |
Multiple excluding the largest = (total fair value − largest fair value) ÷ (total cost − largest cost)
In Excel, with cost in B2:B8 and fair value in C2:C8: =(SUM(C2:C8)-MAX(C2:C8))/(SUM(B2:B8)-INDEX(B2:B8,MATCH(MAX(C2:C8),C2:C8,0))). Rank by fair value, not cost: the position that matters is the one the NAV depends on.
The largest position by fair value is Brightline Software at 60,600. Take it out: the other six cost 98,000 and are carried at 93,800. Their multiple is 93,800 ÷ 98,000 = 0.96x, against 1.37x for the whole portfolio.
| Measure | Largest holding | Portfolio | Share |
|---|---|---|---|
| Cost | 15,000 | 113,000 | 13.3% |
| Fair value | 60,600 | 154,400 | 39.2% |
| Unrealised gain | 45,600 | 41,400 | 110.1% |
By cost the fund looks diversified: no position above a fifth. By fair value one company is two fifths of the portfolio, and with the second largest, 54.8 per cent. By gain, the measure that matters for the multiple, one company accounts for more than all of it. The other six positions are 4,200 below cost in aggregate, with three of them, Pellham, Redmere and Thornfield, carried 11,200 below what was paid. That shortfall is the numerator of a loss ratio, the companion test for the downside of the same schedule.
Why above 100 per cent is possible. A share of gain above 100 per cent simply means the rest of the portfolio is losing money on paper. It is the most compact way to say that the fund's reported performance is a single-asset story.
| Markdown of the largest | Its fair value | Portfolio fair value | Portfolio multiple | Change in portfolio value |
|---|---|---|---|---|
| 0% | 60,600 | 154,400 | 1.37x | 0.0% |
| 10% | 54,540 | 148,340 | 1.31x | −3.9% |
| 20% | 48,480 | 142,280 | 1.26x | −7.8% |
| 30% | 42,420 | 136,220 | 1.21x | −11.8% |
Each 10 per cent on the one mark moves the whole portfolio value by about 3.9 per cent. The break-even is more reassuring than the headline suggests, though: the portfolio stays above cost as long as Brightline is worth at least 19,200, which is still 1.28x its own cost and a 68.3 per cent fall from the current mark. The concentration is real, but the cushion is wide. Both facts belong in the same sentence of an investor's notes.
Recompute the multiple without the largest position by fair value: 1.37x becomes 0.96x here, and one holding carries 110.1 per cent of the gain. Then find the break-even, 19,200, so the concentration is stated with its cushion. The free reporting pack and working documents for this book include the schedule of investments with the multiple excluding the largest, and the NAV calculation shows where that schedule sits in the statements.
From the schedule of investments, by fair value rather than cost, and by share of the unrealised gain. In the illustrative fund the largest holding is 13.3 per cent of cost but 39.2 per cent of fair value and 110.1 per cent of the gain. Recomputing the multiple without it, 0.96x against 1.37x, is the single most informative concentration figure.
Yes, whenever the other positions are in aggregate below cost. In the illustrative portfolio the largest holding shows a gain of 45,600 while the fund's total unrealised gain is 41,400, because the other six positions together are 4,200 below cost. That is 110.1 per cent.
Solve for the value that makes total fair value equal total cost. In the illustrative fund the other six holdings are worth 93,800 against a total cost of 113,000, so the largest must be worth at least 19,200, which is 1.28x its own cost. That is a 68.3 per cent fall from its 60,600 mark.
