A subscription credit facility is a fund-level revolving line of credit secured by the uncalled capital commitments of a fund's limited partners rather than by the fund's underlying assets. The fund draws on it to bridge capital calls, funding acquisitions and expenses immediately and calling investor capital later to repay the balance.
How a Subscription Credit Facility Works
A subscription credit facility works by lending against a borrowing base built from investors' uncalled commitments, not the fund's real estate. According to fund finance counsel at Mayer Brown, the borrowing base aggregates each included investor's uncalled commitment and applies a discount factor, so a fund may receive availability equal to 90 percent of a rated investor's uncalled commitment.
The collateral is contractual, not physical. The fund pledges its right to issue capital calls and receive the proceeds. Mayer Brown notes this lets a lender step into the fund's shoes and call capital directly from investors if the fund defaults, without liquidating any property. The lender is repaid by investors, so credit rests on investor quality.
Because the fund can draw immediately and call capital quarterly, the facility delays the moment investor cash leaves their accounts. That delay is the mechanism that raises reported internal rate of return, since IRR is time-weighted and a later, shorter capital outlay compresses the period over which returns are measured.
Why a Subscription Credit Facility Matters
A subscription credit facility matters because it separates when a deal is funded from when investors actually pay, and that gap reshapes both operations and headline returns. Sponsors gain speed at closing and issue fewer, larger capital calls. Investors face a reported IRR that can look materially stronger than the same deals financed with immediate calls.
For an operator or an allocator reading a track record, the distinction is not cosmetic. A fund that borrows on a subscription line for several quarters before calling capital shortens the measured holding period baked into IRR. Two funds with identical property-level cash flows can post different fund-level IRRs purely from how aggressively each used its line.
The facility also carries real cost. Interest and unused-line fees accrue on borrowed and available capital, and those costs reduce the multiple even as they lift IRR. Reading a return without knowing the line usage behind it is reading half the picture.
Example
The example below shows the same 10 million dollar equity deal returning 13 million dollars, financed two ways: an immediate capital call versus a subscription line drawn at close and repaid by a call one year later. Property cash flows are identical. Only the timing of investor cash changes.
Item | Without a sub line | With a sub line |
|---|---|---|
Investor cash out at close (year 0) | 10,000,000 | 0 |
Line drawn at close | 0 | 10,000,000 |
Investor cash out at capital call | 0 | 10,000,000 at year 1 |
Total distributions at exit (year 3) | 13,000,000 | 13,000,000 |
Investor capital period | 3.0 years | 2.0 years |
Approximate net IRR | 9.1% | 14.0% |
Without the line, investors hold capital in the deal for three full years, and 13 million on 10 million over three years is roughly a 9.1 percent IRR. With the line, the fund borrows at close and investors do not fund until year one, so their cash is deployed for two years. The same 30 percent total gain earned over two years of investor capital computes to roughly a 14.0 percent IRR. The equity multiple is 1.3x in both cases, before line interest. The IRR moves by about five points on timing alone.
Variations and Edge Cases
Subscription credit facilities vary mainly in tenor, borrowing base construction, and how the resulting IRR distortion is disclosed. The core edge case is transparency: a short bridge is routine, while a line held open for many quarters can inflate reported IRR in ways limited partners cannot see without specific disclosure.
Variation or edge case | What changes |
|---|---|
Short bridge use | Line repaid within one or two quarters. Minimal IRR distortion, treated as operational convenience. |
Extended use | Line held many quarters before calling capital. Larger IRR lift, higher fees, greater scrutiny. |
Recallable capital | If the fund agreement allows returned capital to be recalled, the borrowing base can be preserved; counsel advises the agreement state this explicitly. |
Hybrid or NAV blend | Later-life facilities may lean on asset value rather than commitments, changing the collateral and risk. |
The Institutional Limited Partners Association addressed the distortion directly. Its 2020 guidance recommends that net IRR be reported both with and without the use of the subscription facility, starting from the reporting period ending June 30, 2020, alongside disclosure of the facility limit, borrowing term, collateral base, interest rate, and fees.
Subscription Credit Facility vs Capital Call
A subscription credit facility is often confused with a capital call. A subscription credit facility is the fund's borrowing arrangement, a revolving line secured by uncalled commitments. A capital call is the fund's demand that investors send in a portion of their committed capital. The facility bridges the timing; the capital call ultimately repays it.
Put plainly, the line lets the fund spend before investors pay, and the capital call is the moment investors finally pay. One is a credit instrument held with a bank. The other is a contractual obligation owed by the investor. The facility exists precisely to postpone and consolidate the capital calls that stand behind it.
Frequently Asked Questions
What secures a subscription credit facility?
A subscription credit facility is secured by the uncalled capital commitments of the fund's investors, not by the fund's real estate or other assets. The fund pledges its right to call capital and receive the proceeds, so repayment depends on investor creditworthiness rather than property performance.
Does a subscription credit facility increase IRR?
Yes. By letting the fund draw at close and call investor capital later, a subscription credit facility shortens the time investor cash sits in the deal. Because IRR is time-weighted, the same total return earned over a shorter capital period produces a higher internal rate of return.
What does ILPA recommend about subscription lines?
The Institutional Limited Partners Association recommends that funds report net IRR both with and without the subscription line, effective from the reporting period ending June 30, 2020, and disclose the facility limit, borrowing term, collateral base, interest rate, and associated fees.
