Systematic Biases in Private Equity Returns (with Simon Hayley)
Private Equity (PE) has grown into a substantial asset class, but there remain major problems with measuring PE fund returns. Investors continue to use the internal rate of return (IRR) as a key measure of fund performance. It is well known that early returns of cash can have a substantial impact on fund IRRs, but the magnitude and causes of this effect have not previously been systematically analysed. We demonstrate that the IRR is affected by two systematic biases: a convexity bias, and a “quit-whilst-ahead” bias arising because the returns on PE projects tend to covary with their durations. Both bias the IRRs of PE funds upwards. Using a range of parametric and non-parametric estimation techniques, we show that these biases boost fund IRRs by between 2 and 4% per annum ─ a very significant proportion of the average net PE fund IRR (around 12% per annum). Fund cash multiples and PMEs become similarly biased if they are annualized to try to make them comparable with other assets. We further demonstrate that alternative performance measures which have been suggested by practitioners are also biased, which confirms how poorly understood these effects are. Failure to take proper account of these biases is likely to lead investors into badly misinformed investment decisions.
Fair Value Measurement and Private Equity Fund Interim Valuations
Private equity investors require accurate estimates for the market value of their investments to perform optimal fund allocations and correctly diversify their portfolios. Since private equity investments are mostly privately held and do not have an active market valuation, these estimates rely on the subjective valuations of the fund managers. Previous research documents inaccurate valuations that lag behind the real intrinsic values of the investments. This paper shows that adopting fair value accounting increases the accuracy of the interim fund valuations of buyout funds significantly. This increase is not temporary, is accompanied by the increased valuation effort of the private equity funds and is robust to the possible confounding effects of the global financial crisis. Beneficial effects of local fair value measurement standards spill over to the funds in other geographies, mainly due to peer pressure effect. Fair value measurement eliminates the significant heterogeneity in valuation quality stemming from the difference in fund investor profiles.
