HarbourVest Private Equity Benchmark

HarbourVest’s proprietary benchmarks, created by the firm’s Quantitative Investment Science group, track the performance of PE and venture-owned companies. HarbourVest releases benchmark performance for companies in the following categories: Global Buyouts; US Buyouts, a subset of the Global Buyouts category; and US Venture Capital. An investment benchmark is similar to a scorecard, used to measure how well an investment is performing compared to a relevant counterpart. The HarbourVest benchmarks are based on HarbourVest’s proprietary dataset of over 64,000 investments that have been held in PE funds, representing more than $3.7 trillion of capital invested collectively as of March 31, 2025.

HarbourVest Private Equity Benchmarks (“HV PE Benchmarks”). Market analysis is not representative of any HarbourVest product. The HV PE Benchmarks reflect a compilation of PE partnership and transactional data drawn from internal and external sources and related estimated valuations of such companies by HarbourVest for the illustrated period (which in turn are based on HarbourVest’s subjective assumptions).  The HV PE Benchmarks represent net performance based on an all-in fees and expenses assumption of 500 basis points. The actual fees and expenses applicable to the underlying investments included in the HV PE Benchmarks may be materially higher than the assumed fees and expenses, which would lower the returns. The HV PE Benchmarks data universe information has been developed internally based on information obtained from sources believed to be reliable; however, HarbourVest does not guarantee the accuracy, adequacy or completeness of such information or HarbourVest’s related valuation estimates or assumptions, which may be materially inaccurate.  The HV PE Benchmarks are intended to be representative of the broader PE market and do not reflect any views, analysis, or recommendation by HarbourVest with respect to any particular investment and are not representative of the investment performance of any HarbourVest investment or the experience of any investor in any HarbourVest product. Past performance is not indicative of future results.

Continuation solutions encompass a host of transaction types in which a GP secures interim liquidity and/or additional primary capital for their LPs in a strongly performing asset, or set of assets, that the GP will continue to own and control. Specifically, they include continuation funds, new funds created by GPs for the purpose of acquiring the asset(s) that continue to be managed by the same GP and capitalized by one or several secondary buyers, or equity recapitalizations involving a direct equity or structured equity investment into a portfolio company. These transactions can also include a parallel investment from the GP’s latest fund into that same pool of assets (a “cross-fund trade”).
