Defeasance Comprehensive Guide to Flexible Debt Repayment
881 reads · Last updated: December 2, 2025
Defeasance is a financial arrangement in which a borrower sets aside sufficient funds or securities (such as government bonds) in a trust account to ensure the future repayment of debt. This arrangement legally renders the original debt as repaid, thereby releasing the borrower from the obligation. Defeasance is commonly used in corporate bonds and mortgage-backed securities to remove the borrower's legal responsibility without actually repaying the debt. This allows the borrower greater flexibility in managing their assets and liabilities while ensuring that creditors receive their due payments on time.
Core Description
- Defeasance is a financial technique that removes a borrower's legal obligation on debt by substituting a portfolio of government securities in a trust, which mirrors the loan's scheduled payments.
- It allows borrowers to unlock restrictive covenants, release liens, and facilitate property sales or refinancing when prepayment is limited or costly, while investors still receive timely debt service payments.
- Defeasance is common in corporate bonds, commercial mortgage-backed securities (CMBS), municipal finance, and other capital market transactions that value flexibility and risk mitigation.
Definition and Background
Defeasance is a specialized financing tool in which a borrower sets up an irrevocable trust and deposits sufficient cash or high-quality securities—typically government bonds or Treasury bills—into the trust. This portfolio is carefully structured so the cash flows generated match exactly the remaining debt service payments of the borrower's outstanding liability (principal and interest).
Once the trust arrangement is established and legally perfected, the borrower is considered to have “defeased” the debt. The trust then assumes responsibility for servicing the debt until maturity, and the borrower's obligations—such as covenants or liens—are released, even though the bonds or loans technically remain outstanding. This separation of legal and economic responsibility has roots in English common law, where an obligation could be nullified by the performance of a specified act.
Historical Context and Evolution
Defeasance emerged decades ago in structured debt markets and has become increasingly relevant as capital markets have grown in complexity. Early applications were in U.S. municipal and corporate bonds with high prepayment penalties or restrictive call features. As capital markets developed further, defeasance transactions became more sophisticated, especially within commercial real estate (with the rise of CMBS) and project finance.
Since the 1980s, regulatory and accounting standards have evolved, affecting how defeasance transactions are displayed on corporate balance sheets. Generally, current accounting rules require legal discharge for true derecognition of the liability. Additionally, improvements in technology and financial modeling have increased the efficiency of defeasance transactions, benefiting market participants with time and cost savings.
Calculation Methods and Applications
Present Value and Cash Flow Matching
The technical core of defeasance is the accurate matching of debt service cash flows with the income from securities placed in trust. This includes:
- Calculating the present value (PV) of all remaining payments (both principal and interest) using the following formula:
PV = Σ CFt / (1 + rt)twhere CFt represents scheduled debt service at time t, and rt indicates the relevant risk-free spot rate from the government yield curve. - Employing linear programming or optimization techniques to create a portfolio of government securities that matches the payment dates and amounts, minimizing cost while meeting all timing requirements.
Key Application Areas
| Sector | Rationale for Defeasance | Example Use Case |
|---|---|---|
| Corporate Bonds | Remove old, high-coupon, non-callable debt | Issuer funds a trust to exit debt, facilitating asset sales or new issuance |
| CMBS/Commercial Real Estate | Permit sale/refinance during lockout, unlock equity | Property owner defeases CMBS loan to sell asset without penalty |
| Municipal Finance | Advance refundings, remove restrictive covenants | Municipality defeases bonds to align payments with new capital budgets |
| Project Finance | Transition from construction to operational phase | Project sponsors defease debt at asset sale or refinancing stage |
| Utilities/Energy | Simplify legacy obligations, facilitate rate cases | Utility defeases pollution-control bonds for balance sheet optimization |
| Asset Securitization | Manage collateral pools, support asset substitutions | MBS sponsor replaces loans with government bonds to maintain cash flow scheduling |
| Mergers & Acquisitions | Deliver unencumbered assets at closing | REIT buyer defeases underlying mortgages to ensure clean title |
| Financial Institutions | Improve capital metrics, optimize funding costs | Bank defeases legacy trust-preferred securities |
Example (Fictionalized for illustration):
A U.S. logistics REIT intends to sell a warehouse encumbered by a USD 50,000,000 fixed-rate CMBS loan with five years remaining. Prepayment is prohibited, but defeasance is permitted. The REIT works with advisors to model the remaining debt service, purchases U.S. Treasury securities that match the payment schedule, and deposits them into a bankruptcy-remote trust. After closing, the lien is released, allowing the sale to proceed. The CMBS note remains outstanding, with bondholders continuing to receive timely payments from the escrow.

Comparison, Advantages, and Common Misconceptions
Comparison with Other Techniques
| Feature | Defeasance | Prepayment | Refinancing | Novation |
|---|---|---|---|---|
| Liability Status | Technically outstanding, but economic liability removed | Fully paid, liability extinguished | New loan replaces the old | Original obligor replaced |
| Cash Source | Trust-funded by government securities | Cash from borrower | Cash from new loan | New obligor's payment |
| Flexibility | Releases covenants, unlocks asset | No restrictions if allowed | Dependent on new terms | Requires lender consent |
| Investor Cash Flows | Unchanged, from trust | Cease upon prepayment | New debt terms apply | Same as before |
Advantages
- Releases restrictive covenants and liens, providing operational and strategic flexibility.
- Preserves timely payment to bondholders through government-backed cash flows.
- Facilitates asset sales, restructurings, M&A, or refinancing where direct prepayment is blocked.
- May improve credit metrics and ratings if legal release is recognized.
Disadvantages
- The cost of assembling the collateral portfolio may be substantial, particularly in low interest rate environments or unfavorable yield curves.
- Additional fees may include those for advisors, legal counsel, trustees, and verification agents.
- Errors in cash flow matching or use of ineligible securities can invalidate the transaction.
- Defeasance may introduce tax and accounting complexities, especially across jurisdictions.
- Once completed, restructuring or prepaying the position again becomes significantly more complex.
Common Misconceptions
Confusing Defeasance with Prepayment
Defeasance does not “pay off” the loan. Although the borrower's obligation is legally extinguished, the debt remains outstanding and the lender continues to receive payments from the escrow, not the borrower.
Assuming All Obligations Are Released
Certain obligations, such as tax indemnities, representations, or residual carve-outs, may survive defeasance and require ongoing attention.
Assuming Defeasance Always Saves Money
In some market environments, the cost of acquiring escrow securities may exceed other exit or restructuring costs, so a thorough net present value (NPV) analysis is essential.
Using Ineligible Collateral or Poor Matching
Ineligible securities or cash flow mismatches can cause the transaction to be rejected, resulting in legal issues or financial penalties.
Ignoring Tax and Accounting Effects
Defeasance may impact the deductibility of interest, trigger gains or losses, and affect balance sheet presentation, depending on regulations.
Practical Guide
Step-By-Step Execution
1. Feasibility Analysis
Review loan documents to ensure that defeasance is allowed and identify any restrictions on timing or collateral. Calculate the present value of remaining payments using current risk-free yield curves.
2. Team Assembly
Engage specialist advisors, legal counsel, a trustee, a defeasance consultant, and, if necessary, a securities dealer. Proper coordination is essential.
3. Structuring the Escrow Portfolio
Select government securities (such as U.S. Treasuries or SLGS) that closely match the timing and amount of each required debt payment. Use modeling tools to minimize cost and ensure sufficiency.
4. Documentation & Approvals
Prepare and review the defeasance agreement, escrow trust agreement, and any required legal, tax, or accountant opinions. Obtain approvals from the trustee and servicer as needed.
5. Closing and Funding
Purchase the securities and transfer them into the trust. Obtain verification from a cash-flow sufficiency agent. Upon legal perfection, execute lien-release or covenant-release documents.
6. Ongoing Compliance
Monitor trust cash flows to ensure all payments are made on schedule. Address any obligations, indemnities, or reporting requirements that remain after defeasance.
Virtual Case Study (Illustrative Only)
Suppose a U.S. REIT wishes to sell a shopping center encumbered by a non-callable USD 30,000,000 CMBS loan with three years remaining. Prepayment is not possible, but defeasance is permitted post-lockout. The REIT hires a consultant to identify a basket of U.S. Treasury notes that match all remaining payment dates and amounts. These are placed into a bankruptcy-remote trust. Upon verification and completion of documentation, the property lien is released, the asset is sold, and payments to CMBS investors continue from the escrow. (This scenario is hypothetical and not investment advice.)
Important Tips
- Proceed only if expected savings and strategic benefits clearly outweigh all transaction and administrative costs.
- Use only eligible government securities, and rigorously test the matching of all payment flows.
- Consult counsel early to address indenture restrictions and secure necessary approvals.
- Time the execution to market conditions, and consider hedging interest rate exposure if appropriate.

FAQs
What is defeasance in finance?
Defeasance is a structured transaction in which a borrower deposits high-grade securities into a trust that generates cash flows mirroring the outstanding debt’s payments, allowing legal release from obligations while investors continue to receive scheduled payments.
How does defeasance differ from prepayment or refinancing?
With defeasance, a borrower’s obligation is discharged by substituting collateral, but the original debt remains outstanding until maturity. Prepayment retires the debt early with cash, whereas refinancing replaces it with a new loan and terms.
Which assets are eligible for the defeasance trust?
Typically, only top-rated government securities such as U.S. Treasuries or SLGS are eligible, as specified in loan or bond documentation to avoid reinvestment and credit risk.
Who benefits from defeasance?
Borrowers gain flexibility to sell or refinance, while investors maintain the predictability and security of government-backed payment streams. Trustees, servicers, and advisors may also benefit from associated fees.
What are the main costs and risks of defeasance?
Costs include purchasing the government securities portfolio, professional fees, and possible negative carry. Risks may arise from mismatches in cash flows, ineligible collateral, administrative delays, or unfavorable tax and accounting treatment.
When is defeasance permitted?
Only when allowed by loan or bond documents, typically after a lockout period and subject to conditions such as no existing default, delivery of required opinions, and rating confirmations.
What are the accounting and tax consequences?
Legal release of liability is generally needed for balance sheet derecognition. Tax treatment may involve gain/loss recognition and reporting of escrow income, varying by jurisdiction and requiring expert review.
Does defeasance always save money?
No. The cost-effectiveness of defeasance depends on the interest rate environment, transaction fees, and debt terms. A detailed net present value (NPV) analysis should be conducted in advance.
Conclusion
Defeasance is an established liability management tool serving borrowers, investors, and capital market participants by substituting a portfolio of government securities for outstanding debt. When structured and executed appropriately, it offers flexibility for asset sales, refinancing, or corporate actions, while providing continuity of payments for investors.
However, these benefits must be carefully measured against significant transaction costs, technical and legal complexities, and potential accounting or tax issues. Unlike traditional prepayment or refinancing, defeasance maintains payment streams and regulatory compliance, and is well-suited for capital market environments where covenants or lockouts limit early repayment options.
A thorough understanding of defeasance mechanics, careful transaction planning, and advice from qualified professionals are essential to realizing its value and mitigating associated risks. As debt markets continue to evolve, defeasance remains a strategic option for unlocking value and optimizing finance operations across sectors.
