Private equity is often described as an asset class. It is more accurately a set of ownership strategies bound together by a common structure: pooled capital, a long holding period, active involvement in the businesses owned, and an exit that determines the outcome.
Understanding it means understanding two separate things — what the strategies actually do, and how the fund structure distributes the results between managers and investors. The second matters more to an investor return than most presentations imply.
The strategies
Leveraged buyouts acquire controlling stakes in mature, cash-generative businesses, typically using a mix of equity and debt. Value is intended to come from operational improvement, growth, debt paydown, and eventual sale — often at a higher multiple than was paid. This is the largest part of the market by capital.
Growth equity takes minority or control positions in companies that are expanding and need capital, generally with less leverage and less operational intervention than a buyout.
Venture capital funds early-stage companies, accepting that most investments will fail and that returns depend on a small number of outcomes being very large. Its risk and return distribution is fundamentally different from buyout, and treating the two as one asset class obscures more than it clarifies.
Special situations, distressed, and turnaround strategies acquire businesses in difficulty, where the return depends on restructuring rather than growth.
The fund lifecycle
Nearly all traditional private equity uses the same closed-end structure.
Fundraising. Investors make commitments rather than paying in. A commitment is a binding obligation to fund when called.
Investment period. Typically several years, during which the manager sources deals and issues capital calls. Uncalled commitments are dry powder that investors must hold liquidity against — a genuine cost that is easy to overlook.
Holding period. The manager works with portfolio companies. This is where the strategy either creates value or does not, and it is largely invisible to investors except through periodic valuations.
Harvest. Companies are sold — to strategic buyers, to other sponsors, through public offerings, or increasingly into continuation vehicles. Proceeds are distributed.
Wind-down. The fund terminates, typically after a stated life of around a decade, often extended.
Two consequences follow that investors consistently underestimate. First, capital is committed for a very long time and cannot be recalled — the only exit before wind-down is a secondary sale. Second, the investor does not control timing in either direction: not when capital is called, not when it comes back.
Fees and the waterfall
This is where investor outcomes are actually determined, and it deserves more attention than the strategy discussion usually receives.
Management fee. Charged on committed capital during the investment period, then generally on invested capital as the fund harvests. Note what this means: fees are paid on money not yet invested, which is a real drag in the early years.
Carried interest. The manager share of profits, typically paid only above a preferred return through a distribution waterfall. The structural details matter enormously:
- Whole-of-fund (European) vs. deal-by-deal (American) waterfalls determine whether carry is paid only after all capital is returned, or as individual deals exit. The difference in investor outcome can be substantial.
- The GP catch-up tier, and its rate.
- The clawback provision, and whether it is meaningfully secured.
Other economics. Transaction fees, monitoring fees, and other amounts paid by portfolio companies to the manager, and what proportion is offset against the management fee. Offset arrangements vary and are worth reading rather than assuming.
An investor comparing two funds on headline fee percentages while ignoring waterfall structure and fee offsets is comparing the wrong things.
Measuring returns honestly
Private equity performance measurement is genuinely contested, and the contest matters.
IRR is the industry standard and is sensitive to cash flow timing. Use of a subscription line to defer capital calls raises reported IRR without changing a single underlying investment. ILPA has encouraged disclosure both with and without the facility effect, and a manager who cannot provide it is worth a question.
Multiples — MOIC, DPI, TVPI, RVPI — ignore time but reveal what a manager actually returned versus what it says it still holds. DPI is the least manipulable figure in the set.
Public market equivalent analysis asks what the same cash flows would have earned in a public index. It is the comparison that most directly answers whether the illiquidity was worth accepting.
Unrealised marks carry the same caveat as everywhere else in illiquid strategies: they are estimates produced by an interested party. A record dominated by RVPI is substantially unproven. See evaluating a sponsor track record.
Vintage year matters heavily. Comparing funds across different vintages without adjusting for the environment they invested into is not a like-for-like comparison, and dispersion between managers within the same vintage is wide.
The risks worth naming
Leverage. Buyouts use debt, and debt amplifies both directions. A portfolio company that would have survived a downturn unlevered may not survive it levered.
Illiquidity, without a floor. There is no repurchase program and no gate — there is simply no exit for a decade unless a secondary buyer is found, at whatever price they offer.
Valuation opacity. Interim reporting is based on marks. An investor cannot verify them.
Manager dispersion. The gap between good and poor managers in private equity is wide, considerably wider than in most public strategies. Access to the better managers is itself constrained, which means the returns commonly cited for the asset class are not available to every investor who wants them.
Fee drag. Compounded over a decade, the full economic load is larger than the headline suggests.
Blind pool risk. Investors commit before knowing what will be bought.
Getting access
Traditional funds require accredited and often qualified purchaser status, with high minimums and K-1 reporting.
Broader access now exists through registered vehicles — interval and tender offer funds pursuing private equity and secondaries strategies, and evergreen structures that eliminate capital calls. These genuinely widen access. They also carry different fee mechanics, transact at NAV rather than at realisation, and offer capped rather than absent liquidity. Neither route is strictly better; they are different trades.

The cluster
- Private equity secondaries — buying and selling existing fund interests
- Continuation vehicles — the fastest-growing exit route
- GP-led secondaries — manager-initiated transactions
- Co-investment — investing alongside a fund

Frequently Asked Questions
What is private equity?
Investment in companies that are not publicly traded, typically through funds that acquire ownership stakes, hold them for several years while working to increase value, and then sell. The category spans leveraged buyouts of mature businesses, growth equity in expanding companies, and venture capital in early-stage ones.
How does a private equity fund work?
Investors commit capital rather than paying it upfront. The manager calls capital as investments are made, generally over an investment period of several years, holds the portfolio, and returns proceeds as companies are sold. Most funds have a stated life of around a decade with extension provisions.
What fees do private equity funds charge?
Typically a management fee on committed capital during the investment period and on invested capital afterward, plus carried interest — a share of profits above a preferred return, paid through a distribution waterfall. Fund-level expenses, transaction fees, and monitoring fees paid by portfolio companies also affect net outcomes.
How is private equity performance measured?
Usually through internal rate of return alongside multiples such as MOIC, DPI and TVPI. Each measure conceals something the others reveal: IRR is sensitive to cash flow timing, multiples ignore time entirely. Public market equivalent analysis compares the same cash flows against a public index and is among the more honest comparisons available.
Who can invest in private equity funds?
Traditional funds are generally limited to accredited investors and often to qualified purchasers, with high minimums and long lock-ups. Broader access has come through registered vehicles such as interval and tender offer funds pursuing private equity strategies, which carry their own trade-offs on cost and liquidity.
