Capital-Call and Subscription Lines: What LPs and GPs Actually Pay

A rule meant to force more disclosure about these facilities was adopted in 2023 and struck down entirely less than a year later. The facilities themselves didn't go anywhere.

In August 2023, the SEC adopted a package of rules that would have forced private fund advisers to disclose more about how they use subscription credit facilities, among other things. Less than a year later, in June 2024, the Fifth Circuit Court of Appeals vacated the entire rule package, ruling the SEC had exceeded its statutory authority. The facilities themselves, capital-call lines and subscription lines, kept operating exactly as before, because the underlying product was never the target; the disclosure rule was. That regulatory whiplash is a useful way to understand where this corner of fund finance actually sits today: a large, normal, functioning part of private-fund operations with comparatively thin, and currently contested, disclosure requirements around it.

What the facility actually is

A subscription credit facility, also called a capital-call line or subscription line, is a revolving credit facility extended to a private equity or similar fund. Its collateral is not the fund's portfolio companies or investments; it is the unfunded capital commitments of the fund's limited partners. A bank lends against the LPs' contractual obligation to fund capital when called, which lets the fund's general partner draw cash immediately to close a deal or cover an expense, and formally call capital from LPs afterward, on the GP's own schedule rather than the deal's.

Why GPs actually use them

Speed is the obvious reason: a subscription line lets a fund move on a time-sensitive deal without waiting on LP wires to clear. The less obvious reason is administrative and reporting convenience: bundling several smaller draws into fewer, larger capital calls reduces the operational burden on both the GP and the LPs processing those calls.

The real cost: not just interest, but reported returns

Every subscription line carries genuine interest cost, ultimately borne by the fund's limited partners as a fund expense, even though the GP is the one drawing the facility. That part is easy to see.

The harder-to-see part is the effect on reported performance. Internal rate of return (IRR) is time-weighted: it measures returns against how long capital was actually deployed. Delaying a formal capital call with a subscription line, while the underlying investment is already generating returns, shortens the period LP capital is counted as "at work" in the IRR calculation, which can push a fund's reported IRR meaningfully higher than an equivalent multiple-on-invested-capital (MOIC) figure would suggest, since MOIC doesn't weight for time the same way. Two funds with identical actual investment performance can report different IRRs purely based on how aggressively each used subscription-line bridging, which is exactly the kind of distortion that made this a live regulatory concern in the first place, vacated rule notwithstanding.

The current regulatory state, and why it's worth re-checking

The 2023 SEC rules would have required, among other things, enhanced quarterly statements and clearer disclosure of fees, expenses, and facility usage specifically so LPs could evaluate exactly this kind of IRR effect. The Fifth Circuit's June 2024 vacatur eliminated that requirement in full. As of this writing, the SEC's own website confirms the rules are not in effect, though the agency retained the option to seek further rehearing or appeal to the Supreme Court. This is a live legal question, not a settled one, and anyone relying on the current disclosure regime for subscription-line usage should confirm the state of that litigation directly rather than assume this page's snapshot still holds.

What to ask a fund's GP

How much of the fund's reported IRR is attributable to subscription-line bridging versus actual underlying investment performance, and what does the MOIC look like on its own?
What is the current outstanding balance and average usage period on the fund's subscription line, and how has that trended across the fund's life?
What interest rate and fees is the fund actually paying on its subscription line, and how is that cost allocated across LPs?
Given the vacated 2023 SEC rules, what voluntary disclosure practice does the fund follow regarding subscription-line usage, if any?

Frequently asked questions

What is a capital-call or subscription line of credit?

It's a revolving credit facility extended to a private equity or similar fund, secured primarily by the unfunded capital commitments of the fund's limited partners rather than by the fund's underlying investments. It lets a general partner draw cash to fund a deal or cover expenses immediately, then formally call capital from LPs later, or bundle multiple smaller calls into one larger, less frequent call.

Why do funds use these instead of just calling capital directly?

Speed and administrative convenience for the GP, primarily: a subscription line lets a fund move on a deal without waiting for LPs to wire funds, and it can smooth out the frequency of capital calls LPs otherwise have to process. It also has a real effect on reported performance metrics, since delaying a capital call while a deal is already generating returns can inflate a fund's calculated IRR relative to calling capital immediately.

Are subscription lines regulated?

There is no comprehensive federal rule governing them specifically. The SEC adopted a package of Private Fund Adviser Rules in August 2023 that would have required enhanced disclosure around fund expenses and facility usage, but the Fifth Circuit Court of Appeals vacated those rules in their entirety in June 2024, finding the SEC had exceeded its statutory authority. As of this writing, that vacatur stands, though the SEC retained the option to appeal, so the current regulatory status is worth re-checking before treating this as settled.

Who actually bears the cost of a subscription line?

Ultimately, the fund's limited partners, through the fund's expenses, even though the facility is drawn by the general partner. This is one of the specific points of investor and regulatory scrutiny: whether the cost and IRR effect of a subscription line is disclosed to LPs clearly enough for them to evaluate it, particularly when a facility is used for something closer to ongoing leverage than short-term bridging.

Does using a subscription line change a fund's actual returns, or just how they're reported?

Both, in different ways. The line itself carries real interest cost, a genuine drag on returns. Separately, delaying capital calls with a subscription line shortens the time LP capital is technically 'at work' in the fund's own IRR calculation, which can make a fund's reported IRR look higher than an equivalent multiple-on-invested-capital figure would suggest, since IRR is time-weighted and MOIC is not.

How is a subscription line different from a NAV loan?

They sit on opposite sides of a fund's life. A subscription line is collateralized by LPs' unfunded capital commitments and is typically used early, to bridge deals before capital is formally called. A NAV loan is collateralized by the fund's actual portfolio holdings and is typically used later, once most capital is already called and invested, when there's little uncalled commitment left to borrow against. Some funds use both at different points, but they are not substitutes for each other.
