How is the weighted average multiple in a Level 3 table calculated?

The fair value note's weighted average weights by equity, so sales and leverage move it as much as marks do.

In most private fund accounts the weighted average in the Level 3 inputs table is weighted by each investment's fair value: Σ (fair value × multiple) ÷ Σ fair value. On an illustrative five-company portfolio worth 252.0 that gives 10.59x, against a simple average of 9.50x and an aggregate multiple of 9.51x. Because the weights are equity values, the figure moves with sales and leverage as much as with marks: selling one company at its carrying value takes it to 8.98x with no mark changed.

The quantitative table in the fair value note lists, for each valuation technique, the unobservable input, its range and usually a weighted average. Readers treat the weighted average as the fund's valuation multiple and compare it year on year. It is a useful number once you know what it weights, and a misleading one if you do not.

The portfolio

Five illustrative Level 3 investments valued on EV/EBITDA comparables. Millions.

The note would print: market comparables, EV/EBITDA multiple, range 7.0x to 13.5x, weighted average 10.59x. Everything else in the table above is what the note does not show.

The calculation, step by step

Step 1: weight by fair value

Σ fair value × multiple = 90.0 × 13.5 + 63.0 × 10.0 + 35.0 × 8.0 + 48.0 × 9.0 + 16.0 × 7.0 = 2,669.0
Weighted average = 2,669.0 ÷ 252.0 = 10.59x

Excel: =SUMPRODUCT(FV,Multiple)/SUM(FV)

Step 2: the alternatives the note could have used

Simple average of the five multiples: 47.5 ÷ 5 = 9.50x
Weighted by the fund's share of enterprise value (523.0 in total): 10.08x
Aggregate: share of EV ÷ share of EBITDA = 523.0 ÷ 55.0 = 9.51x

The aggregate is the multiple at which the fund is effectively paying for its share of the portfolio's EBITDA. It is more than a turn below the reported 10.59x, because Alder, the most expensive company, also has the largest equity value and carries 35.7 per cent of the fair value. Elm, the cheapest and most indebted, carries 6.3 per cent although it has the largest EBITDA. A high multiple on the same debt leaves more equity, so weighting by fair value leans towards the expensive companies.

The result: what moves the number

Four events and what each does to NAV and to the reported weighted average.
EventFair value afterWeighted averageChange
Opening252.010.59x0.00

Elm marked down one turn240.010.75x+0.16
Every company down half a turn224.510.22x−0.37

Three readings follow.

The like-for-like test. Reweight this year's multiples by last year's fair values, over the companies held at both dates. If that figure is unchanged and the reported one fell, the move came from the composition of the portfolio, not from the marks. With Alder sold and nothing remarked, the like-for-like average of the four remaining companies is 8.98x at both dates.

What to ask for

The note gives one range and one average, and the range is set by its two extremes. To use the figure, ask the manager for three things: the basis of the weighting, in words; the weighted average recomputed on last year's holdings; and EBITDA and net debt by company, which turn a multiple into an equity sensitivity. The last is what the NAV sensitivity to one turn of EBITDA multiple needs, and the movements in the same Level 3 balance are read in the Level 3 roll-forward.

The common mistake

Reading a lower weighted average multiple as more conservative valuation. In this portfolio the figure fell by 1.62 turns with no company remarked, and rose by 0.16 when a company was written down by three quarters. The weighted average describes the mix of what the fund holds at the reporting date, weighted by equity; it is not an index of how hard the marks were pushed.

Takeaway

Recompute the weighted average yourself from the schedule of investments, weighting by fair value, and set it beside the simple average and a like-for-like figure before drawing any conclusion.

Questions readers ask

What does the weighted average in a Level 3 unobservable inputs table mean?

It is the average of the input, here the EV/EBITDA multiple, across the investments valued with that technique, usually weighted by each investment's fair value. In the illustrative fund it is 2,669.0 divided by 252.0, or 10.59x. Because fair value is equity value, highly levered companies get little weight even when they are large businesses.

Why did a fund's weighted average multiple fall if nothing was written down?

Because the weights changed. Selling the highest-multiple company at exactly its carrying value removes 35.7 per cent of the weight at 13.5x, and the average falls from 10.59x to 8.98x. Reweighting the remaining multiples at last year's fair values shows the same 8.98x, which confirms the move is composition, not valuation.

Can a markdown increase the weighted average multiple?

Yes. Cutting one turn off a thinly capitalised company destroys most of its equity and so most of its weight. In the example, Elm loses 12.0 of fair value, 75.0 per cent of the position, and the weighted average rises from 10.59x to 10.75x even though NAV fell by 4.8 per cent.
