Defeasance commercial mortgage collateral swap

Defeasance commercial mortgage treatment is a collateral substitution in which the borrower pledges government securities that replicate remaining scheduled loan payments, allowing the lender or REMIC to release its lien on the real property while the mortgage obligation continues for investors.

Treasury Regulation section 1.860G-2(a)(8) provides that if a REMIC releases its lien on real property securing a qualified mortgage, the mortgage ceases to be a qualified mortgage on the release date unless specified conditions are met. For defeasance, the mortgagor must pledge substitute collateral consisting solely of government securities as defined in section 2(a)(16) of the Investment Company Act of 1940; the mortgage documents must allow the substitution; the lien must be released to facilitate disposition of the property or another customary commercial transaction, and not as part of an arrangement to collateralise a REMIC offering with non mortgage obligations; and the release must not occur within two years of the REMIC startup day.

How defeasance commercial mortgage substitution operates

In CMBS and other capital markets commercial mortgages, loan documents and the pooling and servicing agreement set the defeasance path. The borrower (often through a successor borrower SPV) purchases a portfolio of eligible securities sized so that cash flows match remaining principal and interest, including any balloon at maturity. Those securities are pledged into an account under lender or custodian control. The real property lien is released, freeing the asset for sale or refinancing, while bondholders continue to receive the scheduled mortgage cash flows from the securities package rather than from property DSCR based operations.

IRS materials accompanying REMIC regulation history describe defeasance as replacement of underlying real property collateral with government securities whose payments match the mortgage's payments. The two year startup lockout and document permission requirements are intended to ensure defeasance is a customary commercial exit tool rather than a device to collateralise a REMIC with non real estate assets from the outset.

Open market pricing of the securities portfolio determines the cash cost. When yields on eligible securities are below the loan coupon, more securities (a higher cash outlay) are typically required to replicate the higher loan payments. When securities yields are higher, the required portfolio can cost less relative to remaining principal. Transaction costs also include legal fees, rating agency correspondence where required, servicer fees and securities bid offer costs.

REMIC constraints and document conditions

Qualified mortgage continuity after lien release turns on meeting every regulatory defeasance condition. If documents do not permit substitution, or if release occurs within two years of startup, or if substitute collateral is not limited to qualifying government securities, the mortgage can cease to be a qualified mortgage. Federal Register restatements of section 1.860G-2(a)(8) repeat the government securities, document permission, customary transaction, and two year timing tests.

Loan level lockout periods often exceed the REMIC two year minimum. Many CMBS loans prohibit defeasance for an initial closed period and then permit it until a window near maturity when open prepayment or yield maintenance may apply instead. A covenant breach or event of default can suspend defeasance rights until cured, depending on the documents.

Successor borrower structures are common. The original borrower or a newly formed bankruptcy remote entity assumes the continuing debt secured by the securities, isolating the released real estate owner from ongoing mortgage obligations after closing of the defeasance.

Defeasance versus yield maintenance and assumption

Yield maintenance is a cash prepayment formula that pays off the loan. Defeasance is a collateral swap that leaves the loan outstanding. Assumption transfers the existing loan to a property buyer without releasing the debt through securities. OCC CRE handbook discussion of interest rate risk notes that, in the absence of prepayment penalties, CRE financing can expose banks to options risk when borrowers refinance as rates fall. Capital markets loans address that convexity concern through lockouts, yield maintenance or defeasance so that investors retain expected duration.

Portfolio lenders may use defeasance less often than CMBS trusts because balance sheet loans can accept cash payoff with a make whole. Where a loan sits in a REMIC, defeasance is frequently the prescribed path to release real estate while protecting qualified mortgage status and investor cash flow continuity.

Security package transformation

Before defeasance, the security package centres on the mortgage, assignments of leases and rents, and related property collateral. After defeasance, priority shifts to perfected security over the government securities account and the contractual rights to the matched payment stream. Real property remedies cease once the lien is released. Credit monitoring after closing is securities custody and payment matching rather than property NOI surveillance.

Process administration typically involves the master servicer, a securities intermediary, counsel for borrower and trust, and often a defeasance consultant who sizes and executes the securities bid. Rating agency or certificate holder notices may be required under the pooling and servicing agreement. Trade day execution locks the securities cost, so rate moves between pricing indication and settlement change the cash required. Borrowers refinancing or selling must coordinate that securities purchase with the real estate closing so lien release and title transfer occur in the correct order.

Institutional summary

Defeasance commercial mortgage practice is a regulated collateral substitution: government securities replace real estate as security, the loan remains outstanding, and REMIC rules preserve qualified mortgage status only if statutory conditions including the two year startup lockout are met. It is distinct from cash yield maintenance prepayment and from loan assumption on a sale.
