Subscription credit lines can raise IRR while adding financing costs
Subscription facilities delay LP contributions while adding interest and fees. A higher reported IRR can therefore coexist with an unchanged investment outcome and a lower net multiple.
A subscription credit facility is borrowing supported by a private fund’s capital-call rights and investors’ uncalled commitments under the financing arrangement. It lets the fund make investments before collecting the corresponding cash from limited partners, or LPs.
The facility changes the timing of LP cash flows. It does not by itself improve the portfolio company’s operating performance.
Delayed contributions shorten the measured investment period
Take an investment costing $100 at year zero and returning $150 at the end of year two. With an immediate LP contribution and no other cash flows, the LP’s annual internal rate of return is approximately 22.47%. The cash multiple is 1.50x.
Now finance the same $100 purchase with a subscription line for one quarter of a year. Assume simple annual interest of 8%, no fees, and repayment of principal and interest through a single LP contribution after that quarter.
The interest is $100 × 8% × 0.25 = $2. The LP contributes $102 at year 0.25 and receives the same $150 at year two. The measured LP holding interval is 1.75 years.
The annual IRR is approximately 24.65%, calculated as (150/102) raised to the power 1/1.75, minus one. The cash multiple falls to approximately 1.47x because $150 is divided by $102 rather than $100.
A higher IRR can coexist with less value per dollar contributed
The investment’s purchase and exit were identical in both cases. The financed case added $2 of cost but removed the first quarter from the LP’s contributed-capital period.
The higher IRR therefore describes the financing-adjusted cash-flow schedule. It does not establish a better acquisition price, greater operating growth, or a higher exit value.
The effect is conditional. A different borrowing period, interest rate, fee schedule, or distribution pattern can reduce rather than increase IRR. The arithmetic must use the actual contribution and distribution dates.
Uncalled commitments still create an LP obligation
An LP whose contribution is delayed has not necessarily been released from its commitment. It still needs a liquidity plan for the eventual call under the fund agreement.
The LP can retain or invest cash until called, which can have value outside the fund return calculation. It also faces uncertainty about call timing. The appropriate assessment includes both the fund’s financing cost and the LP’s own use of the temporarily retained cash.
Report operating results separately from financing effects
A useful comparison shows fund performance with and without the facility’s effect and identifies interest, fees, borrowing duration, and the supported commitments. Portfolio-level returns answer a separate question from LP-level net returns.
The second-order effect is that a financing choice can change the metric used to judge investment skill. IRR remains a valid description of specified cash flows, but interpreting it requires identifying who supplied the cash during the period omitted from the LP contribution record.
Questions
- Can a subscription line raise IRR without improving the investment?
- Yes. Delaying LP contributions can shorten the measured holding period enough to raise IRR even after interest reduces the net cash multiple.
- Does a higher IRR mean the facility added economic value?
- No. The result must be assessed alongside financing costs, net multiple, timing risk, and the LP’s use of cash retained before the call.
- Are subscription lines backed by the same assets as NAV facilities?
- No. Their defining security bases differ: subscription facilities rely on commitments and capital-call rights; NAV facilities rely on portfolio value or related proceeds under their financing terms.
