A GP fund is a private investment partnership in which a General Partner manages the money and makes every investment decision, while Limited Partners supply most of the capital and stay out of operations. The vehicle is almost always structured as a limited partnership, runs for roughly 10 to 12 years, and earns returns by buying private assets such as companies, real estate, or infrastructure, improving them, and selling them at a profit. The General Partner is paid through an annual management fee and a performance-based share of profits called carried interest.
The Two Roles Inside the Fund
Every GP fund has two classes of participant, and the split between them is the whole point of the structure.
The General Partner runs the fund. That means sourcing deals, negotiating acquisitions, working with portfolio company management, choosing when to sell, handling regulatory filings, and reporting to investors. The GP owes a fiduciary duty to act in the financial interest of the Limited Partners, which is not abstract: it prohibits favoring personal deals over fund opportunities, charging hidden fees, or concealing conflicts. Breach of that duty is one of the most common grounds for LP litigation.
The GP also carries unlimited liability for the fund’s obligations. If debts exceed assets, creditors can reach the GP’s own resources. In practice, almost every modern GP is itself organized as an LLC or corporation so that exposure is contained inside the GP entity rather than falling on the individuals running it. The entity is still on the hook; the corporate shield protects the people behind it.
Limited Partners put up the capital. The LP roster for institutional funds typically includes pension plans, university endowments, insurance companies, sovereign wealth funds, and high-net-worth individuals. Their role is financial. They commit a dollar amount, receive periodic reports, and collect distributions when investments are sold. Crucially, their financial exposure is capped at what they committed. No creditor can reach beyond that number, which is the mirror image of the GP’s unlimited liability.
LPs do not wire their full commitment on day one. The GP issues capital calls as deals close, drawing down committed capital in installments so cash does not sit idle. Missing a call is serious. Standard penalties in the Limited Partnership Agreement include interest on the unpaid amount, forced sale of the defaulting partner’s interest at a discount, and in the worst case forfeiture of the LP’s entire existing stake. GPs sometimes extend grace periods for temporary cash-flow issues, but the contractual penalties exist so the fund can close deals on schedule.
The GP’s Own Money in the Fund
Limited Partners expect the GP to invest alongside them. The industry benchmark for this commitment is 1% to 5% of total fund size. A GP raising a $500 million fund would typically put in $5 million to $25 million of its own capital. When the GP has meaningful personal money at risk, its incentives line up with LP returns and the temptation to take reckless swings with other people’s money drops.
Why the Limited Partnership Form
Most GP funds organize as limited partnerships, though some use an LLC format. The partnership form does two things at once: it creates the clean split between the controlling GP and the passive LPs, and it avoids double taxation. Profits and losses pass through directly to each partner. There is no tax at the fund level.
Every year, each partner receives a Schedule K-1 reporting their share of the fund’s income, deductions, and credits.1Internal Revenue Service. Schedule K-1 (Form 1065) – Partners Share of Income, Deductions, Credits, Etc. Partners then report those figures on their own returns. The fund entity itself is a legal vehicle that holds portfolio assets, executes transactions, and distributes proceeds, and it is separate from the GP’s management company, which handles staffing and overhead.
Who Can Invest in a GP Fund
These funds are not open to the general public. Federal securities law limits participation to investors who clear specific financial thresholds, and most funds rely on registration exemptions that narrow the pool further.
The baseline is accredited investor status. For individuals, that means income above $200,000 per year, or $300,000 jointly with a spouse, in each of the two most recent years with a reasonable expectation of the same going forward, or net worth above $1 million excluding a primary home. Those thresholds come from SEC Rule 501 of Regulation D and have not been adjusted for inflation since they were set.
Many larger funds require the higher standard of qualified purchaser. An individual qualifies by owning at least $5 million in investments. An entity managing money on a discretionary basis needs at least $25 million in investments.2Legal Information Institute. 15 USC 80a-2(a)(51) – Qualified Purchaser Funds limited to qualified purchasers can accept more investors without triggering registration as an investment company. Before evaluating any GP fund, an investor needs to know which of these two standards applies.
The Fund’s Life Cycle
A GP fund follows a predictable arc across roughly 10 to 12 years, broken into distinct phases. The timeline drives when LPs write checks and when they get paid back.
Fundraising
The GP markets its strategy and secures binding capital commitments. This phase can run a few months for an established firm or well over a year for a first-time manager. Once a minimum threshold is reached, the fund holds its first close and can begin investing. Additional closes may follow. Early investors sometimes receive reduced fees for committing before the strategy is proven.
Investment Period
The investment period runs roughly three to six years. During this window the GP deploys committed capital, issues most of the fund’s capital calls, and builds a portfolio aligned with its stated strategy, whether that is leveraged buyouts, growth equity, venture-stage companies, or real estate.
Value Creation
Once the portfolio is assembled, the GP shifts from buying to improving. This phase overlaps with the later years of the investment period and extends through roughly years four to eight. The GP works with portfolio company management on operational improvements, strategic acquisitions, cost reductions, or repositioning for sale. New investments largely stop, and so do capital calls. This is where the GP’s operational skill either justifies the fees or does not.
Harvest and Liquidation
In the final years the GP sells portfolio assets and distributes proceeds. Exits happen through sales to strategic buyers, sales to other private equity firms, or initial public offerings. The GP controls the timing and method. Proceeds go to partners on a pro-rata basis under the waterfall provisions in the partnership agreement. If some assets remain unsold when the term expires, the GP can request one or two one-year extensions. Once every asset is liquidated and final distributions are paid, the fund dissolves.
How the General Partner Gets Paid
GP compensation has two components, and they create different incentives.
The Management Fee
The management fee is an annual charge that covers the GP’s operating costs: salaries, office space, travel, legal work, and due diligence. Industry data shows the median fee during the investment period sits around 1.75% of committed capital, though recent vintages have trended lower. After the investment period, most funds step the fee down to around 1.50% and shift the calculation base from committed capital to invested capital, which is a smaller number. Some funds charge a flat rate throughout the fund’s life with no step-down, so this is worth confirming in the partnership agreement.
Carried Interest
Carried interest is the GP’s share of investment profits and is where the real money is made. The standard split is 20% of profits to the GP and 80% to the LPs, though the ratio can shift for top-performing managers or first-time funds. The GP cannot collect any carry until the fund clears a preferred return, sometimes called a hurdle rate, which guarantees LPs a minimum annualized return on invested capital before profit-sharing begins. That threshold is commonly set at 7% to 8% compounded annually.
The tax treatment of carried interest is a running policy debate. Under Section 1061 of the Internal Revenue Code, capital gains allocated through a carried interest qualify for the lower long-term capital gains rate only if the underlying assets were held for more than three years.3Internal Revenue Service. Section 1061 Reporting Guidance FAQs Gains from assets held three years or less are recharacterized as short-term and taxed at ordinary income rates. This three-year rule, added by the Tax Cuts and Jobs Act, replaced the standard one-year holding period that applies to most other investments.
How Proceeds Flow: The Waterfall
The waterfall determines the order in which money comes back to partners, and two models dominate. Under the European waterfall, LPs receive all of their invested capital plus the full preferred return before the GP takes any carried interest. This is the more LP-friendly structure, because the GP profits only after investors are fully made whole across the entire fund.
The American waterfall lets the GP collect carried interest deal by deal. Sell one investment at a big profit and the GP can take its 20% cut immediately, without waiting for the fund to clear the hurdle overall. The catch is a clawback provision: if later deals underperform and total returns fall short of the preferred return, the GP must return the excess carry it already took. Clawback enforcement can get messy in practice, which is one reason many institutional LPs push hard for the European structure during negotiations.
Tax Wrinkles for Certain Investors
Pass-through taxation is efficient for most partners, but it creates specific problems for two groups.
Pension funds, endowments, and IRAs are tax-exempt, but that exemption has limits. When a tax-exempt entity invests in a partnership that runs a trade or business or uses debt to generate income, the resulting profits are classified as unrelated business taxable income. A fund that uses leverage to acquire portfolio companies, which describes most buyout funds, will generate some UBTI for its tax-exempt LPs. Those investors must file IRS Form 990-T and pay tax at trust rates directly from the investment account. For an IRA, the account itself pays the tax as a separate taxpayer under its own EIN. If the IRA holder pays the tax personally instead of from the account, the IRA risks losing its tax-sheltered status entirely.
Non-U.S. investors face a parallel issue. If the fund is engaged in a trade or business within the United States, each foreign partner is treated as engaged in that trade or business as well.4Internal Revenue Service. Effectively Connected Income (ECI) Income allocated to the foreign LP becomes effectively connected income, taxed at graduated U.S. rates, with withholding required and a U.S. tax return to file. Many funds address both problems with parallel structures, blocker corporations, or offshore feeders, each with its own costs.
The Documents That Govern the Relationship
Three documents form the legal foundation of every GP fund, and any investor should read all three before committing.
The Limited Partnership Agreement is the master contract between the GP and all LPs. It governs capital commitments, distribution waterfalls, fee terms, removal rights, extension provisions, and everything else that defines the economic relationship. Standard LP protections written into the LPA include the ability to remove the GP for cause such as fraud or gross negligence, advisory committee seats for the largest investors, and the right to audited financials on a set schedule.
The Private Placement Memorandum is the disclosure document. It describes the investment strategy, risk factors, financial projections, use of proceeds, and the securities law exemptions the fund relies on.
The subscription agreement is the contract each LP signs to formally commit capital. It typically includes the investor’s representations about accredited investor or qualified purchaser status.
Larger or strategically important LPs often negotiate additional terms through side letters. These supplemental agreements can include fee discounts, enhanced reporting, co-investment rights, or transfer provisions. A most-favored-nation clause is common, giving an LP the right to elect any better term granted to another investor of equal or smaller size. Side letters are standard in institutional fundraising, and any investor putting in a significant amount should expect to negotiate one. Any experienced allocator will have legal counsel review the LPA in detail before signing.
