From Pension Fund to Buyout to Exit: The Machine Behind Private Equity
Private equity works by raising money from pension funds and other large investors, buying companies with that money plus a large amount of borrowed debt, improving them over several years, and then selling them for more than the firm paid.
That is the simple version. The full picture is far more interesting: a private equity firm can double its investors’ money on a company whose value rose only 20%, collect fees before any profit is made, and take cash out of a business without ever selling it.
This guide explains every part of the machine, from where the money comes from and who is allowed to invest, to leveraged buyouts, fees, exits, and the regulations behind the industry. FRC has no relationship with any private equity firm and earns no commission from any investment: we explain how the industry works so you can understand it for yourself.

What Private Equity Is
Private equity is the business of buying ownership stakes in companies that are not listed on a public stock exchange, or taking listed companies private. Instead of buying a few shares on the market, a private equity firm typically buys control of the whole business.
Control is the point. Owning the company outright lets the firm choose the management team, set strategy, change how the business is financed, and decide when and how to sell.
The term covers several strategies. Buyouts, where a firm acquires a mature company, usually with debt, are the largest part of the industry and the focus of this guide. Growth equity funds take minority stakes in fast-growing companies, and venture capital, often grouped under the same private markets umbrella, backs early-stage startups.
Where the Money Comes From
Most of the money in a private equity fund does not come from billionaires. It comes from pension funds, university endowments, insurance companies, sovereign wealth funds, family offices and wealthy individuals.
The private equity firm that runs the fund is the general partner, or GP. The investors who supply most of the capital are the limited partners, or LPs. The GP makes the investment decisions, while the LPs generally have no say in how individual companies are run.
That creates a chain most people never see. A teacher contributes to a state pension plan, the pension plan commits part of its assets to a private equity fund, and the fund uses that money to buy and run companies. Some of the capital behind a buyout ultimately belongs to ordinary workers saving for retirement.
Raising that money is a regulated activity. Interests in private funds are securities, and the people who market them to investors generally do so through a FINRA-registered broker-dealer. The Securities Industry Essentials exam is the starting point for anyone entering that side of the industry, with the Series 82 covering private placements specifically and the Series 7 covering the full range of securities.
Who Can Invest in a Private Equity Fund
Most private equity funds are open only to accredited investors. Under the SEC’s definition, an individual generally qualifies with a net worth above $1 million, not counting their primary home, or income above $200,000 a year, or $300,000 together with a spouse or partner, in each of the last two years.
Since the SEC updated the definition in 2020, knowledge counts too. Individuals who hold the Series 7, the Series 65 or the Series 82 in good standing also qualify as accredited investors, whatever their wealth.
Many larger funds set a higher bar. To avoid registering as an investment company under the Investment Company Act of 1940, a fund typically relies on one of two exemptions. Section 3(c)(1) limits a fund to 100 beneficial owners, while Section 3(c)(7) allows more investors but requires every one of them to be a qualified purchaser, which for an individual means owning at least $5 million in investments.
How a Fund Is Built: Commitments, Capital Calls and the Ten-Year Life
When a pension fund invests in private equity, it does not hand over all its money on day one. It makes a commitment, a legally binding promise to provide up to a set amount when asked.
The GP then makes capital calls, drawing down portions of each commitment as deals are found. A $100 million commitment might be called as $20 million for a first acquisition, $25 million for a second, $15 million for a third, and the rest over the following years.
A traditional fund has a life of about ten years, often with extensions. The first five years or so are the investment period, when the GP buys companies, and the remaining years are spent improving and selling them.
Investors are usually locked in for that whole period. Fund interests can sometimes be sold on the secondary market, but that typically needs the GP’s approval and often comes at a discount. Private equity investors trade away liquidity in exchange for access to investments that take years of active ownership to develop.
This timing creates what the industry calls the J-curve. In the early years, fees are being paid and companies are being bought and restructured, so returns often look negative. Later, as companies are sold, returns rise, tracing the shape of the letter J.
The Leveraged Buyout, Step by Step
The leveraged buyout, or LBO, is the engine of the buyout industry. The firm buys a company using a combination of its fund’s money, called equity, and borrowed money, called debt.
Here is a simplified example. A firm buys a company for $1 billion, putting in $400 million of equity and borrowing $600 million. Crucially, that debt sits on the acquired company’s balance sheet, so the company itself must make the interest payments and repay it from its own cash flow.
Years later, the firm sells the company for $1.2 billion. By then, the company’s cash flow has reduced the debt to $400 million.
After repaying the remaining debt, the equity is worth $800 million. Ignoring interest, fees and taxes, the firm’s investors have doubled their $400 million, even though the company’s value rose by just 20%. That is the power of leverage: it turns a modest rise in company value into a much larger percentage gain on the equity.
The Three Engines of Private Equity Returns
Private equity returns come from three sources, and the strongest deals use all three. The first is earnings growth: increasing the company’s profits through better pricing, cost control, new products or new markets.
The second is debt reduction. Every dollar of debt the company repays from its own cash flow increases the value left for the equity holders when the business is sold.
The third is multiple expansion, and it surprises most people. Suppose a firm buys a business earning $50 million a year in EBITDA, a common measure of operating profit, and pays six times that figure, or $300 million.
Years later, earnings are still $50 million, but a buyer is now willing to pay eight times EBITDA. The company is worth $400 million, $100 million more, without earning a single extra dollar. Multiples can rise because a business looks less risky, more predictable or more attractive to buyers, and they can just as easily fall.
What Leverage Does to Returns, in Both Directions
Leverage cuts both ways, and the numbers show exactly how sharply. Take a company bought for $100 million with $40 million of equity and $60 million of debt.
If the company sells for $150 million five years later, with the debt paid down to $40 million, the equity is worth $110 million. That is 2.75 times the original investment, or about 22.4% a year. Had the firm bought the same company with no debt at all, the same sale would have returned 1.5 times its money, or about 8.4% a year.
Now reverse it. If the company is sold for $80 million with all $60 million of debt still outstanding, the equity is worth just $20 million, a 50% loss. Without debt, the same fall in value would have meant a 20% loss.
Leverage also puts pressure on the business itself. A company carrying heavy debt has less room to absorb a recession, rising interest rates or the loss of a major customer, which is why some highly leveraged buyouts end in restructuring or bankruptcy.
How a Private Equity Firm Gets Paid
The traditional fee model is known as “2 and 20.” The GP charges a management fee of around 2% a year and takes around 20% of the fund’s profits, known as carried interest.
The management fee is paid regardless of performance. On a $1 billion fund, 2% is $20 million a year, or $100 million over a five-year investment period if the fee base stays the same. That money pays for the firm’s staff, offices and deal costs, and the fee rate often steps down after the investment period ends.
Carried interest is different. It is the GP’s share of the profits, and in many funds it is paid only after the LPs have received their capital back plus a preferred return, often 8% a year.
Terms vary widely between funds, and large investors often negotiate lower fees. But the structure explains why a GP’s incentives can differ from its investors’: the management fee rewards raising larger funds, while carried interest rewards performance.
Taking Cash Out Without Selling: The Dividend Recapitalization
One of the industry’s more controversial tools is the dividend recapitalization. A company owned by a private equity fund borrows new money, say $100 million, and pays it out as a dividend to its owners, including the fund.
The fund receives cash early, without selling the business, and keeps full ownership and any future upside. For the fund’s investors, that can mean money back years before an exit.
The company, however, is left with more debt to service. If business slows or interest rates rise, that extra borrowing reduces its flexibility at exactly the wrong moment. The cash investors received came from new debt, not from new profits.
Buy-and-Build: Assembling a Bigger Company
The company a private equity firm sells is not always the one it bought. In a buy-and-build strategy, the firm acquires a platform business and then adds smaller companies in the same or related industries.
Picture a regional accountancy firm acquired as a platform. Over several years, it buys five smaller firms in neighboring cities, combining their clients, sharing back-office systems and gaining negotiating power with suppliers. The combined group can then be sold as one larger business, often at a higher multiple than the small firms would have fetched individually.
The strategy is popular in fragmented industries such as accounting, dental practices, veterinary clinics and insurance brokerage. Its risks are integration and price: merging different systems, cultures and teams costs time and money, and overpaying for add-on acquisitions can wipe out the gains.
Where Returns Are Won Before the Deal Closes
A large part of a private equity investment’s outcome is decided before the purchase is completed. Before buying, a deal team may spend months on due diligence, examining the company’s financial statements, earnings quality, customer concentration, contracts, liabilities, competitors and management.
The team builds detailed financial models and tests them against difficult scenarios. What happens if sales fall 10%, interest rates rise, or a major customer leaves? How much debt can the business realistically carry?
Price is the decisive variable. A strong business bought at an excessive valuation can produce disappointing returns, while a less glamorous company bought at the right price, with a credible plan for improvement, can do far better.
How Private Equity Firms Sell Companies
The final stage of every deal is the exit, and an IPO is only one of several routes. A firm may sell to a strategic buyer, such as a competitor or a larger company entering a new market, which can often pay more because of the cost savings or growth it expects from combining the businesses.
The firm may also sell to another private equity firm, which is known as a secondary buyout. The new owner may see a different opportunity, such as international expansion or a fresh round of acquisitions, and the same company can pass through several private equity owners over its lifetime.
A growing alternative is the continuation fund. Here, the GP moves one or more companies from an older fund into a new vehicle that it also manages, giving existing investors the choice to cash out or roll their stake forward. It provides liquidity, but it also raises conflict-of-interest questions, because the GP sits on both sides of the transaction.
The Exit Backlog: Private Equity’s Biggest Challenge in 2026
Selling companies has become the industry’s central problem. As of June 30, 2026, PitchBook data showed 33,575 private equity-owned companies unsold worldwide, more than double the 15,923 of a decade earlier, and Bain & Company estimates that unsold portfolio is worth about $3.8 trillion.
Companies are being held longer as a result. Bain reports that the typical buyout is now held about seven years before it is sold, compared with five to six years between 2010 and 2021, and almost 40% of portfolio companies have been held for more than five years.
Investors are feeling it. Distributions, the cash funds return to their LPs, were about 14% of fund value in 2025, according to Bain, the fourth year in a row below 15%. At the current pace of exits, PitchBook estimates it would take about 11 years to sell every private equity-backed company in the United States.
Private Equity and Your 401(k)
Until recently, private equity sat almost entirely outside the retirement accounts most Americans use. That is starting to change.
In August 2025, an executive order titled “Democratizing Access to Alternative Assets for 401(k) Investors” set the policy that retirement savers should have access to funds holding private market investments and other alternative assets. On March 30, 2026, the Department of Labor proposed a rule that would give 401(k) plan fiduciaries a legal safe harbor when selecting investment options that include assets such as private equity.
The proposed safe harbor asks fiduciaries to weigh six factors: expected performance, fees, liquidity, valuation, benchmarking and complexity. As of mid-2026, it remained a proposal rather than a final rule, so check the Department of Labor’s latest guidance before assuming your plan offers private equity. If you are deciding where your own retirement savings should go first, FRC’s guide to the order to invest your money between a 401(k), IRA and brokerage account walks through each account in turn.
How Private Equity Is Regulated
Private equity is less regulated than public markets, but it is far from unregulated. Most private equity firms with $150 million or more in private fund assets in the United States must register with the SEC as investment advisers under the Investment Advisers Act of 1940, which brings fiduciary duties, compliance programs and SEC examinations.
Registered private fund advisers also file Form PF, a confidential report that gives the SEC data on their funds’ size, leverage and risk. Fund interests themselves are usually sold through private offerings under Regulation D, most often Rule 506, which allows firms to raise unlimited amounts from accredited investors without registering the offering with the SEC.
Because funds rely on the Investment Company Act exemptions covered earlier, they avoid the registration, disclosure and diversification rules that apply to mutual funds and ETFs. That flexibility is what allows the use of leverage, concentrated portfolios and long lock-ups, and it is also why access is restricted to investors the law considers able to bear the risk.
Private Equity vs Public Markets
The differences between private equity and investing in public companies come down to liquidity, transparency, cost and control. A share of a listed company can be sold in seconds, while a private equity fund interest can lock up capital for a decade or more.
Public companies publish audited results every quarter and trade at a market price every day. Private companies are valued periodically by the GP, using models and comparable transactions, so reported values can lag reality.
Costs are higher too. An index ETF can cost a few hundredths of a percent a year, compared with management fees around 2% plus carried interest. For most investors, public markets remain the main way to build long-term wealth, and FRC’s complete step-by-step guide to investing in ETFs explains how to get started.
The Deal That Made Private Equity Famous
Private equity’s public image was shaped by one transaction. In 1989, KKR completed its buyout of RJR Nabisco, the tobacco and food giant, for about $25 billion after a fierce bidding war.
It was the largest leveraged buyout in history for well over a decade, and the battle for the company became the subject of the hugely popular book “Barbarians at the Gate.” The deal fixed the image of private equity as aggressive, debt-driven dealmaking, an image the industry has spent decades trying to broaden.
Today the industry is vastly larger and more varied. The largest firms manage buyout, credit, real estate and infrastructure funds, and private equity-owned companies employ millions of people across almost every sector of the economy.
Five Common Misconceptions About Private Equity
The first misconception is that private equity money comes mainly from the super-rich. In reality, pension funds, endowments and insurers supply much of it, often on behalf of ordinary savers.
The second is that private equity firms always pay for companies with their own money. Most buyouts are funded with a large share of debt, and that debt is carried by the company being bought.
The third is that returns depend on dramatic growth. Debt reduction and multiple expansion can generate strong returns even when earnings barely move.
The fourth is that companies always end up on the stock market. Most are sold to competitors or to other private equity firms. The fifth is that private equity is unregulated: most firms are SEC-registered advisers, file Form PF and can sell only to investors who meet strict legal thresholds.
Common Questions
How does private equity make money? Private equity firms earn management fees of around 2% a year and carried interest of around 20% of profits. The funds make money by growing company earnings, paying down debt and selling companies at higher valuation multiples.
What is the difference between a GP and an LP? The general partner is the private equity firm that runs the fund and makes investment decisions. Limited partners are the investors, such as pension funds and endowments, who supply most of the capital.
Can ordinary investors invest in private equity? Most private equity funds are open only to accredited investors. Individuals can also gain indirect exposure through a pension fund, and the Department of Labor has proposed a rule that could make it easier for 401(k) plans to offer private equity.
How long do private equity firms own companies? A typical buyout is now held for about seven years before being sold, according to Bain & Company, up from five to six years between 2010 and 2021.
Is private equity risky? Yes. Leverage magnifies losses as well as gains, investments are illiquid for many years, fees are high and valuations are less transparent than those of listed companies.
