The fund investment period is the three-to-six-year stretch after a private equity or venture capital fund’s final close when the general partner can draw down committed capital and put it into new portfolio companies. It’s the fund’s active buying phase, separate from the later years spent managing and exiting those holdings. The limited partnership agreement (LPA) sets the exact length, the conditions for extending it, and the rules for how capital moves from investors into deals.
How Long the Period Lasts
Most closed-end funds set the investment period at three to six years from the final close, with the length tied to strategy and expected deal pace.1BMO Private Wealth. BMO Private Equity Experience Buyout funds usually land on the shorter end because they target established companies and deals close faster. Venture funds run longer, since sourcing early-stage companies takes more time and deal flow is less predictable.
Almost every LPA includes an extension mechanism, generally one or two additional years, subject to a vote of the limited partners. Most funds require a majority or supermajority of LPs to approve. Some LPAs let the GP extend by a single year without a formal vote if specific conditions are met. These provisions exist because deal flow can dry up in ways nobody predicted at formation, and a rigid cutoff could force the GP to abandon promising deals in the final months.
The schedule matters to investors in practical terms. LPs use it to forecast cash needs, since capital calls cluster during these years and taper off afterward. When the period ends, remaining unfunded commitments shrink dramatically, freeing allocation capacity for new fund commitments.
How Capital Calls Actually Work
When the GP identifies and closes on a deal, it issues a capital call, also called a drawdown notice, to each LP. The notice specifies the dollar amount owed based on the LP’s pro-rata share of total commitments. Industry best practices recommend giving LPs at least ten business days to deliver the funds, and most LPAs follow that standard.2Institutional Limited Partners Association. ILPA Principles 3.0 That window lets institutional investors liquidate short-term holdings or arrange cash.
Once capital lands in the fund’s account, the GP applies it to the purchase price for equity or debt in the target company, plus transaction costs like legal and advisory fees. Deal-level fees typically fall between 0.5% and 1.5% of enterprise value for about two-thirds of acquisitions, with fewer than one in five deals above 1.5%.3Preqin.

Each drawdown reduces the LP’s remaining unfunded commitment. Commit $10 million, watch the fund call $6 million across several deals, and your remaining obligation is $4 million. The GP can only call the rest for purposes the LPA authorizes. Contractual safeguards usually prevent managers from calling more capital than a specific deal needs, because idle cash drags down returns for everyone.
Subscription Credit Facilities
In practice, the clean sequence of “GP finds deal, calls capital, closes deal” is often interrupted by a subscription credit facility, also known as a capital call line. It’s a loan the fund takes from a bank, secured against the unfunded commitments of the LPs. Rather than issue a call at every closing, the GP borrows from the credit line, completes the acquisition, and calls capital later to repay the bank. What began as a short-term bridging tool has grown into a broader cash management strategy, with repayment terms often stretching well beyond 90 days.4Institutional Limited Partners Association.

The effect on reported performance is significant. Because IRR is time-weighted, delaying the moment LPs actually hand over cash compresses the holding period and inflates the return figure. One analysis of 498 funds found a median IRR boost of roughly 200 basis points by year three, though the effect faded to 35 to 45 basis points by the end of the fund’s life.4Institutional Limited Partners Association. Subscription Lines of Credit and Alignment of Interests The total value multiple stays the same either way, but IRR is what drives quartile rankings, and a 200 basis point bump early on can push a fund into a higher tier than the underlying deals justify.
The practice has drawn pushback. A compressed J-curve can trigger carried interest distributions to the GP sooner than warranted, creating potential clawback issues later. Tax-exempt LPs face unrelated business taxable income exposure when credit lines extend beyond a year. In a severe market dislocation, multiple credit lines maturing at once could force overlapping capital calls that strain LP liquidity. ILPA has recommended that GPs disclose both levered and unlevered IRR so investors can evaluate performance without the distortion.4Institutional Limited Partners Association.

Reserves for Follow-Ons and Recycling
Not every dollar goes toward buying new companies. A meaningful share of committed capital, often 10% to 20%, is set aside for follow-on investments in companies the fund already owns. Follow-ons let the fund protect its ownership percentage in a subsequent round or provide growth capital to a portfolio company that needs it. As the investment period nears its end, the LPA typically restricts the GP from initiating entirely new deals, and the remaining capital gets earmarked for follow-on support, management fees, and fund expenses. Follow-on authority usually survives expiration of the investment period; new deal authority does not.
When a fund sells a portfolio company or receives a distribution early in its life, the proceeds can sometimes be redeployed into new investments rather than paid out. This is recycling, and the LPA defines the limits. ILPA’s standards recommend that recycling provisions, including unused recallable distributions, expire at the end of the investment period.2Institutional Limited Partners Association. ILPA Principles 3.0 There is no single universal cap; the amount subject to recycling should have a mutually agreed limit or at least a monitoring threshold so LPs can project cash flows. Common guardrails include limits preventing any single LP’s drawn commitment from exceeding its original commitment, aggregate caps on invested capital as a percentage of commitments, and concentration limits on any single portfolio company.
Recycling can meaningfully increase effective purchasing power. A fund with $500 million in commitments that recycles $75 million from early exits deploys $575 million without asking investors for another dollar. It also delays the return of capital to LPs and extends their exposure, which is why the boundaries matter.
What Happens If an LP Misses a Call
When an LP fails to deliver capital on time, consequences escalate fast. The LPA typically provides a short cure period during which the GP can charge penalty interest. If the default continues, the remedies get severe:
- Forced sale of the LP’s fund interest to other LPs or third parties, usually at the lesser of fair value or prior book value, minus sale expenses.
- Reallocation of the capital call, where another LP or a third party funds the defaulter’s share and receives a preferred interest in that investment, while the defaulter remains liable for future calls.
- Forfeiture of some or all of the defaulter’s accumulated equity in the fund, including voting rights, with that value redistributed to the other partners.
- Offset against future distributions, where the fund withholds profit distributions and applies them against the defaulted amount.
- Liability for the fund’s out-of-pocket expenses caused by the default, including the cost of any bridge financing.
These penalties exist to protect non-defaulting LPs, who would otherwise absorb the cost of a broken call. The harshness is deliberate. When you commit capital, the GP and your fellow investors are counting on that commitment being real, and a default can derail a closing and damage the fund’s reputation with sellers.
When and How the Period Ends
At scheduled expiration, the GP’s authority narrows considerably. New acquisitions stop. The fund shifts into its harvest phase, focused on managing existing portfolio companies and eventually exiting through sales, IPOs, or secondary transactions. The GP keeps authority to make follow-on investments in existing holdings but cannot deploy capital into companies the fund doesn’t already own.
Key Person Events
The investment period can be suspended before its scheduled end by a key person event. A key person clause names specific individuals whose involvement was a primary reason investors committed capital. If one of them leaves the firm or stops devoting sufficient time to the fund, the clause triggers and the ability to make new investments freezes. Roughly 88% of PE funds automatically suspend the investment period when a key person event hits. The suspension is time-limited, typically capped somewhere between three and nine months depending on strategy. During the suspension, the GP and the LP advisory committee work to resolve the situation, either by finding a replacement acceptable to investors or by demonstrating the team can execute without the departed individual. If nothing gets resolved within the window, the investment period can terminate permanently.
No-Fault Removal
Some LPAs include a no-fault divorce clause, which allows LPs to vote to remove the general partner or terminate the investment period without alleging misconduct. The voting threshold is intentionally high, typically 75% to 90% of limited partner interests. Reaching that level of consensus is difficult in practice, since LP bases are fragmented and many investors are reluctant to trigger such a drastic step. The clause still functions as a meaningful check on GP behavior even when never invoked, because the possibility of removal shapes how managers operate.
Management Fee Step-Down
The management fee structure typically shifts at the end of the investment period. During the active years, the GP charges a fee calculated as a percentage of total committed capital, commonly around 2%. Afterward, the fee base changes from committed capital to the cost basis of unexited investments, and the rate often drops as well. A step-down of 20 to 25 basis points from the original rate is a reasonable expectation. The shift reflects that sourcing and closing new deals takes more resources than managing a static portfolio, and it gives the GP a financial incentive to return capital through successful exits rather than letting investments linger.
