Introducing Bison PME

CHANGING HOW YOU THINK ABOUT PME BENCHMARKING

Today Bison is announcing the Bison PME methodology for estimating an IRR for a public market index. The new methodology addresses shortcomings of other public market equivalent (PME) IRR methods and how they handle cash flows. It is built on the work of Steven N. Kaplan and Antoinette Schoar presented in a 2005 paper titled Private Equity Performance: Returns, Persistence, and Capital Flows and introduces a way for estimating public market index cash flows for PME analysis. Investors can use the Bison PME alongside Kaplan Schoar PME to evaluate the speed and size by which alpha is generated relative to public markets.

IRR AND ESTIMATING PME PERFORMANCE

Investors increasingly use PME calculations to determine whether a fund manager is able to outperform the public markets. Where investors calculate public market returns using a time-weighted return calculation, they calculate private equity returns using a money-weighted return calculation (IRR). This has led to apples and oranges comparisons that are hard to evaluate. PME calculations enable investors to calculate a money-weighted return for a public market index.

Most of the PME calculations generate an IRR for a certain market index. This allows for apples to apples comparison of a fund’s IRR versus a public market index. It means, however, that PME calculations are exposed to some of the problems inherent in evaluating returns with only an IRR metric. For instance, we have previously shown that an early distribution can inflate a fund’s IRR and similarly that a fund with a lower TVPI multiple can generate the same IRR as a fund with higher TVPI multiple. There are two major points to remember about why IRR is best understood in combination with a TVPI:

IRR is a money-weighted measure – The IRR calculation is impacted by the size and timing of cash flows. This exposes the calculation to manipulation since multiple variations of cash flows can generate the same IRR. For PME IRR calculations, we believe it is important to replicate the pace of value realization in the fund when calculating an IRR for a public market index. At the same time, the PME calculation has to be sensitive to the impact of the market on the cash flows.

IRR measures speed and not size of returns – The IRR calculation assumes that realized returns can be re-invested at the same rate of return. This means that a proportionally large distribution occurring early in a fund’s life will have a disproportionate impact on the IRR for the life of the fund. When evaluating a private equity fund, it is important to look at the fund’s IRR alongside its TVPI multiple. This standard should also be followed when conducting PME analysis.

INTRODUCING BISON PME

Bison PME is a calculation that enables investors to measure public market IRR and TVPI performance. We developed the methodology after closely evaluating other PME methodologies and their shortcomings that result from how they handle the private equity fund’s cash flows. Specifically, we believe that it is important to leave constant the speed and proportionate value generated in the fund when calculating a PME IRR. We want to lower the risk of PME IRR being impacted by how IRR is calculated market. Based on early testing of 125 funds, Bison PME showed less volatility than other PME methodologies while accurately reflecting changes in public market index value.

We believe PME methods are important for understanding private equity performance and encourage investors to incorporate it into their fund performance analysis. The Bison PME method is an open standard provided for free. We believe it is best used side-by-side to Kaplan Schoar, but also encourage comparison with other PME methods.

Bison PME is available today for free to all Bison Performance Calculator users.
