Private Equity Subscription Credit Line (NAV Facility) Drag
The Formal Definition
Short- and medium-term debt facilities borrowed by private equity and venture capital funds from investment banks—secured by limited partner capital commitments (Subscription Lines) or fund portfolio investments (NAV Facilities)—which inflate reported Internal Rate of Return (IRR) metrics while passing financing interest costs to limited partners.
Reported IRR Mirage = IRR(Delayed Capital Call Cash Flows via Sub-Line) > True Operating IRR(Actual Investment Purchase Date)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Subscription credit lines are how private equity managers manipulate their track records. When the fund buys a company, they don't call your money right away; they borrow cash from an investment bank for eighteen months. Because the clock on their Internal Rate of Return only starts ticking when they actually call your capital, reported IRR looks fantastic, while limited partners pay the bank's borrowing interest."

Real-World Example: Scenario Breakdown
Examining the real numbers for: An institutional allocator committing $5,000,000 to a middle-market private equity fund over a 3-year deployment cycle
| Execution Metric | Audited Sub-Line Allocator | Un-Monitored LP Follower |
|---|---|---|
| Fee / Rate | Institutional placement rate | 2.0% management fee + 20% carry |
| Spread / Buffer | Negotiated LPA covenants capping subscription line borrowing to 180 days and mandating reporting of 'Unlevered IRR' | Fund used a multi-year subscription line to delay capital calls, boosting reported gross IRR from 12% to 19% |
| Execution / Status | Fund called capital promptly; reported IRR reflected the true operational performance of underlying investments | Benchmark hurdles were cleared artificially; manager collected early carried-interest performance fees |
| Total Cost / Result | Audited real economic performance without artificial leverage distortion | Paid performance carry on an artificial IRR boosted by subscription credit leverage |
How Brokers Weaponize This Term
When reviewing private equity or venture fund marketing materials, never rely on reported 'Net IRR'. Demand the 'Total Value to Paid-In Capital' (TVPI / Multiple on Invested Capital) alongside the 'Unlevered Net IRR without Credit Facilities' to see the true cash performance stripped of bank financing leverage.

What is a NAV Facility in private equity?
A NAV Facility is a loan secured by the net asset value of the fund's underlying portfolio companies, used to fund distributions, service existing debt, or finance follow-on investments when capital calls are constrained.
Why do Limited Partners dislike long-duration subscription lines?
Because while it temporarily delays capital calls, it increases the total carried-interest fees paid to the General Partner without increasing the actual total dollars returned to investors.
