Defeasance vs Yield Maintenance: CMBS Prepayment Penalty Comparison
Securities substitution portfolios vs present value cash penalties for commercial mortgage retirement
An underwriting comparison of commercial real estate debt prepayment structures in CMBS and balance-sheet lending. Compares transaction friction costs, interest rate yield spread sensitivity, legal complexity, and property lien release timing.
Technical Tradeoff & Benchmark Matrix
| Underwriting Dimension | Defeasance (Collateral Substitution) | Yield Maintenance (Cash Penalty) |
|---|---|---|
| Legal Mechanism | Real estate lien released; borrower pledges US Treasury bond portfolio to noteholder | Loan is extinguished; borrower pays cash penalty directly to lender |
| Lender Noteholder Structure | Mandated in Securitized CMBS REMIC trusts to preserve bondholder coupon flow | Common in Life Company, Agency (Fannie/Freddie), and Portfolio Bank loans |
| Underlying Security | Non-callable US Treasury obligations (Strips/Notes) customized to match note cash flows | Discounted present value calculation tied to current benchmark Treasury yield |
| Friction Overhead | $50,000 to $100,000 in third-party fees (securities intermediary, CPA accountant, counsel) | Minimal administrative fee ($2,500 to $5,000) for lender payoff statement |
| Interest Rate Environment Impact | Cheaper when Treasury yields are elevated relative to mortgage note coupon | Penalty is lowest (or at contractual floor of 1%) when benchmark yields exceed note rate |
| Closing Timeline | Typically 30 to 45 days to assemble, audit, and pledge Treasury collateral | Immediate (calculated and satisfied within standard 5-to-10 day escrow payoff) |
Frequently Asked Questions & Technical Analysis
Q: Can I negotiate defeasance out of a CMBS loan at origination?
No. CMBS loans are pooled into Real Estate Mortgage Investment Conduits (REMICs). Tax laws and bond rating agencies strictly require defeasance rather than direct prepayments to protect certificate holder cash flows and avoid taxable REMIC disqualification.
Q: What is the minimum prepayment penalty floor under yield maintenance?
Most commercial loan agreements establish a contractual floor of 1.0% of the outstanding principal balance, ensuring the lender receives compensation even if current market interest rates have risen higher than the original loan note rate.
