How BDCs Use Leverage and Fund Their Loan Portfolios
A BDC lends with money it also borrowed. Follow the funding spread, liquidity and maturity ladder beneath the portfolio.
Private Credit Foundations, Lesson 5. Estimated time: 15 minutes.
A Business Development Company (BDC) is a lender with lenders of its own.
That fact sits underneath nearly every yield, dividend and stress scenario in the sector. The BDC raises equity, borrows through facilities or notes, and invests the combined capital in portfolio companies. Leverage can widen the return on shareholder capital when loans perform. It can also make a markdown hit harder and a refinancing window feel much smaller.
What you will learn
By the end of the lesson, you should be able to:
- trace the BDC's funding spread from asset yield to funding cost;
- distinguish revolving facilities from unsecured notes;
- read a debt maturity ladder for refinancing pressure;
- explain how leverage magnifies changes in Net Asset Value (NAV); and
- use asset coverage and liquidity as related but distinct safeguards.
The mechanism in two minutes
Suppose a BDC finances a loan yielding 11% with allocated borrowing that costs 6%. The simple gross spread is five percentage points before management fees, incentive fees, operating expenses and credit losses.
That spread is attractive only while the asset pays, the funding remains available and the BDC stays inside regulatory and contractual limits.
The balance sheet has two clocks. Portfolio loans mature or repay on one schedule. The BDC's own revolvers and notes mature on another. When those clocks disagree, liquidity and refinancing risk enter the room.
The main funding tools
Revolving credit facilities
A revolver provides committed borrowing capacity, usually subject to a borrowing base, covenants and other conditions. It can fund new investments and bridge the timing between originations and repayments.
Undrawn capacity is useful liquidity, but it is not cash and not unconditional. The agreement determines availability.
Unsecured notes
Unsecured notes can diversify funding away from secured bank facilities and often provide fixed-rate, longer-dated capital. They also create a maturity that eventually must be repaid or refinanced.
Fixed-rate debt can insulate near-term funding costs when market rates rise. It can look expensive when rates fall. The value is not merely the coupon; it is the stability and flexibility purchased with it.
Other structures
BDCs may also use secured notes, special-purpose financing vehicles and other arrangements. Each can alter collateral availability, covenants, recourse, cost and maturity risk. Consolidated leverage figures should be reconciled with the notes rather than admired from a distance.
Test the funding structure
Private Credit Foundations · Lesson 5
Can you inspect the lender's lender?
A BDC lends money with money it also borrowed. Test the spread, maturity and liquidity underneath that arrangement.
Asset coverage is not the same as liquidity
The Investment Company Act framework applies asset-coverage requirements to BDC borrowings. Eligible BDCs can operate under a 150% minimum asset-coverage framework after satisfying the applicable approval and disclosure conditions; otherwise the traditional 200% standard applies. Read the issuer's own disclosures before assigning a threshold.
Asset coverage asks how much asset value supports senior securities. Liquidity asks whether the company can meet commitments and obligations when due. A BDC can comply with a ratio and still dislike its maturity calendar.
Why leverage changes the NAV experience
Imagine $150 of assets funded with $50 of debt and $100 of NAV. If asset value falls by $15 while debt remains $50, NAV falls to $85. A 10% asset decline has produced a 15% decline in NAV before other effects.
The example is simplified, but the mechanism is not. Debt has a prior claim. Equity absorbs the change beneath it.
Read the maturity ladder
Ask four questions:
- How much debt matures in the next 12, 24 and 36 months?
- Is that debt fixed or floating, secured or unsecured?
- How much cash and undrawn committed capacity is actually available?
- When are portfolio repayments expected, and how dependable are they?
A resilient ladder spreads maturities, diversifies funding sources and preserves capacity. One very cheap facility can become remarkably expensive if it must be replaced during a closed market.
Apply it to a filing
Open a BDC's debt note and maturity table. List every material facility or note with its balance, rate type, maturity and security position. Then compare total available liquidity with unfunded portfolio commitments.
Finish with one sentence: What must remain true for this funding structure to stay comfortable?
That sentence is the beginning of a stress test.

Key Terms
Business Development Company (BDC): A closed-end company that elects BDC status under the Investment Company Act of 1940 and typically invests in private or smaller public businesses.
Net Asset Value (NAV): Assets minus liabilities, often expressed per share.
Source Notes
The BDC framework follows the U.S. Securities and Exchange Commission's BDC investor bulletin. The statutory asset-coverage framework is governed by Sections 18 and 61 of the Investment Company Act of 1940. Funding balances, covenants, rates, maturities, unfunded commitments and liquidity must be taken from each issuer's current filing and governing agreements.
