You have purchased the cap. The premium has been wired. The confirmation is signed. And your lender is still asking for one more document before they will fund the loan. That document is the Assignment Agreement — and without it, the lender has no legal claim to the cap’s value even though the cap is supposed to be part of their collateral package. This guide explains exactly what the assignment agreement is, what it must contain, who signs it, and why it matters for every party involved.

Everything you need to know about the cap assignment agreement before your next closing.
What the Cap Assignment Agreement Actually Is
An interest rate cap assignment agreement — also called a “Consent and Acknowledgment,” “Cap Assignment,” or “Acknowledgment of Assignment” depending on the lender and jurisdiction — is a legal document that transfers certain rights under the cap from the borrower to the lender. It is always a three-party document, executed by all three parties simultaneously: the borrower (who assigns the rights), the cap dealer (who acknowledges the assignment and agrees to pay accordingly), and the lender (who receives the assignment as collateral).
The assignment agreement does not change any economic terms of the cap. The notional, the strike, the reference rate, the term, and the settlement formula are all unchanged — they remain exactly as specified in the cap confirmation. What changes is who receives the settlement payments and who holds the legal right to enforce the cap in a dispute or default scenario.
Before the assignment agreement
The cap is a bilateral contract between the borrower and the dealer. Only the borrower has rights under it. If SOFR rises above the strike, settlement payments go to the borrower. If the borrower defaults on the loan, the lender has no direct claim to those settlements — they would need to pursue the borrower through foreclosure or other remedies, hoping to capture the cap’s value indirectly.
After the assignment agreement
The lender holds a first-priority security interest in the cap. Settlement payments flow directly to a lender-designated account. The dealer is legally bound to recognise the lender’s interest and to notify the lender before agreeing to any amendments, early terminations, or novations of the cap. The lender can step into the borrower’s position upon a default event.
💡 The core purpose in one sentence: The assignment agreement converts the cap from the borrower’s personal financial asset into a piece of the lender’s collateral package — giving the lender the same direct claim to the cap’s value that they have over the real property itself.
Why Lenders Require the Assignment Agreement
The cap requirement in the loan commitment letter serves a credit function: the cap limits the borrower’s maximum interest expense, protecting the DSCR covenant. But that protection only works for the lender if they have a direct legal claim to the cap’s settlement payments — not just a contractual representation from the borrower that a cap exists.
The collateral gap without an assignment
Imagine a borrower who owns a $15M bridge loan with a $180,000 rate cap assigned to no one. SOFR rises 150bps above the strike. The cap begins generating $18,750 per month in settlements — directly to the borrower’s bank account. The borrower, facing financial difficulties elsewhere, diverts those settlement funds rather than applying them to debt service. The lender has no direct remedy against the cap settlement payments — they only have remedies against the borrower under the loan documents, which are much slower and more expensive to enforce.
With a properly executed assignment agreement, the dealer pays settlements directly into the lender’s lockbox account. The borrower never touches the money. There is no diversion risk, no enforcement delay, and no uncertainty about whether cap settlements will actually offset the interest expense they were meant to address.
Three specific things the assignment agreement gives the lender
1. Direct payment rights
The dealer is contractually required to pay all future settlement amounts to the lender’s designated account rather than to the borrower. This happens automatically on every payment date, without requiring any action by the lender or the borrower. The lender applies those settlements against the monthly interest payment, reducing the effective debt service burden in proportion to the settlement amount.
2. Security interest in the cap asset
The assignment creates a first-priority security interest in the cap agreement itself — including all present and future settlement payments and the cap’s residual market value. This means the cap is collateral: if the loan goes into default, the lender can realise the cap’s value through its security interest, just as it can realise value from the mortgaged property.
3. Step-in rights upon default
If the borrower defaults under the loan, the lender can exercise its step-in rights under the assignment agreement — essentially substituting itself as the cap buyer. The lender continues receiving settlement payments and can manage the cap (sell it, hold it, or terminate it for value) as part of the overall loan workout or recovery process.
The Three Parties: Roles, Rights, and Obligations
Understanding what each party to the assignment agreement signs up for — and what they receive in return — clarifies why the document requires execution from all three entities before it becomes effective.
Role: The entity that purchased the cap and is assigning their rights to the lender as security for the loan.
What they give: Rights to receive settlement payments; right to enforce the cap against the dealer; right to terminate or amend the cap without lender consent.
What they keep: Obligation to maintain the cap per the loan covenant; right to residual cap value upon full loan repayment; right to receive settlements after lender releases the assignment.
Role: The entity receiving the assignment of the cap as collateral security for the loan obligation.
What they receive: First-priority security interest in the cap; direct right to receive settlement payments; step-in rights upon borrower default; right to cap value in a workout scenario.
What they agree to: Release the assignment upon full loan repayment; provide notice to the dealer and borrower before exercising step-in rights (subject to cure periods in the loan agreement).
Role: The entity that sold the cap and must acknowledge the assignment and modify its payment obligations accordingly.
What they agree to: Pay all future settlement payments to the lender’s designated account; not agree to amendments, terminations, or novations without lender consent; notify the lender of any events that materially affect the cap (e.g., events of default under the ISDA Master Agreement).
What they retain: All rights under the cap confirmation (right to receive premium, right to dispute settlement calculations); the economic terms of the cap remain unchanged.
⚠️ All three signatures are required. An assignment agreement executed only by the borrower and the lender — without the cap dealer’s acknowledgment — does not bind the dealer. The dealer will continue paying settlements to the borrower’s account until they formally acknowledge the assignment. The dealer’s execution is not optional or something that can be waived or substituted.
Key Provisions Every Assignment Agreement Must Contain
While assignment agreement formats vary between lenders and jurisdictions, every properly drafted agreement covering the minimum necessary legal ground should contain the following provisions. Each is shown below with an illustrative clause excerpt and a plain-language explanation of what it accomplishes.
This is the operative assignment clause — the sentence that actually transfers the cap rights. The phrase “as collateral security” is critical: it establishes that this is a security interest, not an absolute sale. The borrower still owns the cap in the legal sense, but the lender holds a security interest over it. The enumeration of specific rights (settlement payments, enforcement, termination) leaves no ambiguity about what is included in the assignment.
This clause redirects the payment flow. “Irrevocably” is important — the dealer cannot unilaterally reverse this payment direction without the lender’s written consent. In practice, the lender designates a specific lockbox or restricted account to receive these payments, where they are applied to the borrower’s monthly interest obligation. The borrower should confirm with their servicer how settlements will be credited to ensure proper accounting.
This is the dealer’s four-part acknowledgment. Point (ii) — confirming no prior assignment — is a clean title representation. Point (iii) prevents the borrower from unilaterally modifying or terminating the cap behind the lender’s back. Point (iv) requires the dealer to notify the lender directly of any ISDA default events, ensuring the lender doesn’t learn about a problem through the borrower. Each provision strengthens the lender’s position independently.
This clause restricts what the borrower can do with the cap without the lender’s approval. The four prohibited actions cover every material way the cap could be changed or disposed of: economic amendments, early termination, secondary transfer, and counterparty changes. Any of these actions taken without lender consent would be a breach of the assignment agreement and likely an event of default under the loan agreement as well.
This clause establishes the exit mechanism — how the borrower gets the cap back when the loan is repaid. “Promptly” is the key word for the lender’s obligation. The release triggers the payment redirection back to the borrower, which becomes relevant if the borrower has sold the property and repaid the loan but the cap still has remaining term with residual market value. The borrower needs the formal release to pursue a termination bid or transfer.
Settlement Payment Flow: Where the Money Goes
One of the most practically important effects of the assignment agreement is the redirection of cap settlement payments from the borrower directly to the lender. Understanding exactly how that flow works — and what happens at each step — helps borrowers manage their cash flow expectations and avoid confusion when settlements appear on their loan statements rather than in their bank accounts.
The standard settlement payment path
On each monthly cap settlement date, when SOFR has exceeded the strike during the prior period, the following sequence occurs:
The dealer observes the reset-period SOFR rate, compares it to the strike, and calculates: Notional × Max(SOFR − Strike, 0) × Accrual Fraction. If positive, a settlement notice is issued to both the borrower and the lender (per the assignment agreement’s notification obligations).
Per the payment direction in the assignment agreement, the cap dealer wires the settlement amount to the lender-designated lockbox or restricted account — not to the borrower. This happens 2 business days after the calculation date (standard SOFR derivatives settlement timing).
The lender’s servicer credits the settlement receipt against the borrower’s monthly interest payment for that period. The net effect: the borrower’s effective monthly payment is reduced by the settlement amount, capping their net interest cost at approximately the strike rate level.
The monthly loan statement shows the total interest accrued (at the actual SOFR rate) and the cap settlement credit separately. The net amount owed is the difference. Borrowers should review these statements to verify that settlements are being properly credited — discrepancies can occur if the reference rates or accrual fractions used by the dealer and the servicer differ slightly.
💡 Common confusion point: Some borrowers expect to see cap settlement payments appear in their own bank account and use them to make loan payments. Under an assignment agreement, this does not happen — the payments go directly to the lender. The benefit shows up on the loan statement as a credit, not as a cash receipt. Borrowers who are not aware of this sometimes think their cap isn’t working when it is actually performing exactly as documented.
What Happens to the Cap Assignment in a Default Scenario
The assignment agreement’s step-in rights provision becomes relevant when the borrower defaults under the loan. Understanding this mechanism helps borrowers appreciate the lender’s perspective on cap collateral — and helps lenders understand the practical limits of what the cap assignment can accomplish in a workout.
The lender’s options upon default
Option 1: Continue receiving settlements
If SOFR is above the strike when the default occurs, the cap continues generating settlement payments. The lender can continue receiving these payments during the workout period — they offset some of the ongoing interest accrual on the defaulted loan. The dealer continues paying the lender directly per the assignment agreement until either the cap expires or the assignment is released.
Option 2: Terminate the cap for value
If rates are elevated and the cap has significant remaining term, the lender may choose to terminate the cap and realise its market value as a cash recovery. This requires exercising the step-in rights to substitute as cap buyer, then requesting a termination bid from the dealer. The termination proceeds are applied to reduce the outstanding loan balance or to fund workout costs.
Practical limits of cap recovery
While the cap assignment provides real collateral value, it is typically a modest fraction of the total loan exposure. A cap on a $15M loan might be worth $100,000–$300,000 in a high-rate environment — meaningful as partial recovery, but not sufficient on its own to make the lender whole on a loan with significant principal exposure. The cap assignment is one component of a broader collateral package that includes the real property, personal guarantees, and reserve accounts.
| Default Scenario | SOFR vs. Strike | Cap Residual Value | Lender’s Best Option |
|---|---|---|---|
| Default with 18 months remaining, SOFR elevated | SOFR 120bps above strike | Significant — ITM cap with term | Continue receiving settlements during workout; terminate for value at resolution |
| Default with 6 months remaining, SOFR at strike | SOFR near ATM | Moderate — time value only | Terminate early for the remaining time value; apply proceeds to loan recovery |
| Default with 3 months remaining, SOFR below strike | SOFR 80bps below strike | Minimal — deep OTM, little time value | Let cap expire; recovery from cap is negligible |
The Execution Process: How to Get the Assignment Agreement Done on Time
The single most common cause of cap-related closing delays is the assignment agreement not being ready. The cap confirmation can be executed quickly — the dealer’s operations desk handles it. The assignment agreement requires the dealer’s legal team to review and sign — a completely different internal process with a completely different timeline.
Typical timeline and who does what
As soon as the loan commitment letter is received, request the lender’s preferred assignment agreement template. Most institutional lenders have a standard form they use repeatedly. Receiving this template early gives the dealer’s legal team maximum lead time for their review.
Before engaging any dealer for quotes, confirm they are on the lender’s approved counterparty list and that they can execute assignment agreements in the lender’s required format. Some dealers have pre-approved their standard templates with certain lenders — making execution faster.
Send the lender’s assignment agreement template to the dealer’s legal department — not the sales team. Include the relevant cap economic terms (trade date, notional, strike, termination date) so legal can begin their review immediately. Ask explicitly for a turnaround time estimate.
The dealer’s legal team reviews the template and may propose comments or amendments — particularly if the template is unusual or contains provisions that deviate from their standard language. Most institutional lenders and major dealer banks have seen each other’s templates before and the review is routine. For first-time interactions between a lender and dealer, budget more time.
All three parties execute the final agreed form. In most cases this is done by email exchange of PDF counterparts. The assignment agreement is then delivered to the lender as a closing deliverable, alongside the cap confirmation and premium payment evidence.
🚨 Do not wait until the week of closing to start this process. Dealer legal teams are not always immediately available. If the dealer’s legal team needs 5 business days and you contact them 3 business days before closing, the document will not be ready. Loan funding will be delayed. Start the assignment agreement process the moment the lender’s template is received — treat it as having the same urgency as the cap quote itself.
Common Errors in Cap Assignment Agreements
These are the specific drafting and execution errors that appear most frequently in cap assignment agreements — and that can invalidate the lender’s security interest or create operational problems during the loan term.
| Error | Where It Appears | Consequence | Prevention |
|---|---|---|---|
| Cap terms in the assignment don’t match the cap confirmation | Cap description section — notional, strike, or termination date mismatched | Lender’s security interest may not cover the actual cap; creates dispute in default | Complete the cap confirmation first; copy exact terms into the assignment verbatim |
| Borrower entity name inconsistent with loan documents | Assignor identification in the opening recitals | Chain of title breaks; lender’s security interest may not attach properly | Copy entity name character-for-character from the loan agreement |
| Lender’s payment account details not specified or incomplete | Payment direction clause — account number, ABA, or reference missing | Dealer cannot direct payments; settlements go to borrower instead of lender | Obtain complete wire instructions from lender’s servicer and insert them verbatim |
| Only two parties sign — dealer signature missing | Signature pages — dealer has not executed | Assignment is not effective against the dealer; dealer continues paying borrower | Obtain executed dealer counterpart before certifying document as complete |
| Assignment covers only current term, not extension periods | Scope of assignment — limits coverage to initial cap term | Lender’s security interest lapses when initial cap expires; extension cap not covered | Ensure assignment scope covers the full notional and all periods through cap termination, including any extension |
| Release provisions are missing or require lender unilateral action | Release clause — no procedure for releasing assignment after loan payoff | Borrower cannot recover residual cap value at payoff without lender cooperation on unclear terms | Include a clear, automatic release provision triggered by full loan repayment |
The cap terms that appear in the assignment agreement must match those in the cap confirmation exactly. Use the Waldev cap calculator to model your deal’s specific terms and confirm what notional, strike, and term the cap confirmation should show — before either document is drafted. Discrepancies between the two are far easier to prevent than to fix after execution.
Release at Loan Payoff: Getting the Cap Back
When the loan is repaid — whether through sale, refinancing, or maturity payoff — the lender’s security interest in the cap is released. This is one of the most practically important moments in the cap’s lifecycle for the borrower, because the residual value of the remaining cap coverage becomes recoverable at this point.
The release process
The release of the cap assignment is typically documented in one of two ways. The first approach is a formal written release — a signed document from the lender to both the borrower and the dealer confirming that the assignment is terminated and that the dealer should resume making payments to the borrower. The second approach is triggered automatically by the payoff itself — some assignment agreement forms include a provision that the assignment automatically terminates upon full repayment, without requiring a separate release document.
In practice, the borrower should request a formal written release from the lender at or shortly after the loan payoff closing, regardless of which approach the assignment agreement uses. Having a clear, executed release protects the borrower if any dispute later arises about whether the lender still has a claim to the cap’s value.
Recovering residual cap value after release
Once the assignment is released, the borrower regains full control of the cap. If the cap has significant remaining term — more than a few months — and the current rate environment gives it market value, the borrower should immediately request a termination bid from the cap dealer. The dealer will calculate the current mark-to-market value of the remaining caplets and offer a bid price in cash.
When residual value is likely to be meaningful
SOFR is elevated above the cap strike at the time of payoff, and 6+ months of coverage remain. In this scenario, the remaining caplets have both intrinsic value (the forward curve is above the strike) and time value (uncertainty about future rates). Termination bids of $50,000–$200,000+ are realistic for large notional caps in this environment.
When residual value may be minimal
SOFR is well below the cap strike at the time of payoff, or only 1–2 months remain. In these scenarios, the cap has only minimal time value and the termination bid may be a small amount — but it is always worth checking. Even a $5,000–$15,000 bid on an expiring OTM cap costs nothing to pursue and represents money the borrower would otherwise leave behind.
Assignment Agreement vs. Cap Confirmation: How They Differ
Because both documents are delivered at the same closing and both relate to the same cap, borrowers sometimes conflate the assignment agreement and the cap confirmation. They serve completely different legal functions, are executed by different parties, and govern different aspects of the cap relationship.
| Characteristic | Cap Confirmation | Assignment Agreement |
|---|---|---|
| Legal function | Defines economic terms of the cap transaction | Transfers borrower’s cap rights to lender as collateral |
| Parties | Two parties: borrower + cap dealer | Three parties: borrower + lender + cap dealer |
| Governed by | ISDA Master Agreement | UCC Article 9 (security interest) + general contract law |
| Core content | Notional, strike, reference rate, term, payment dates, premium | Assignment of cap rights, payment direction to lender, dealer acknowledgment, consent requirements, release mechanism |
| Changes cap economics? | Yes — this IS the economic deal | No — economics are unchanged; only ownership and payment flow change |
| Can be amended without the other? | Only with cap dealer consent and typically lender consent per assignment agreement | Only with lender consent; does not affect cap confirmation terms |
| Required for loan closing? | Yes — always | Yes — always (for lender-required caps) |
| Prepared by | Cap dealer (per ISDA standards) | Lender’s counsel (typically from lender’s template) |
Think of the relationship this way: the cap confirmation creates the cap — it is the contract that defines what protection the borrower purchased. The assignment agreement tells everyone where the money goes and who controls the asset. Both documents are essential, and neither substitutes for the other.
Frequently Asked Questions
What is a cap assignment agreement in simple terms?
A cap assignment agreement is a three-party legal document that gives your lender a security interest in your interest rate cap. It requires the cap dealer to pay all settlement payments directly to the lender rather than to you, and it gives the lender the right to step in and control the cap if you default on the loan. Think of it as the document that turns the cap from your personal financial asset into a piece of your lender’s collateral package — similar to how a mortgage turns your property into their collateral.
Why do lenders require an assignment agreement?
Without an assignment agreement, the cap is the borrower’s property — the lender has no direct claim to the settlement payments even if the borrower defaults. The assignment agreement ensures that cap settlements flow directly to reduce the loan’s interest expense (preventing diversion), gives the lender a security interest in the cap’s residual value, and allows the lender to step into the cap in a default scenario. Without it, the lender’s cap requirement accomplishes its DSCR protection goal on paper but fails in practice the moment a borrower is in financial difficulty.
Who are the three parties to the assignment agreement?
The three parties are: (1) the Assignor — your borrowing entity, which purchased the cap and is assigning the rights; (2) the Assignee — your lender, which receives the assignment as collateral security; and (3) the Cap Provider — the dealer bank or intermediary that sold the cap and must acknowledge the assignment and agree to redirect settlement payments. All three must sign for the assignment to be legally effective. A document signed by only the borrower and lender does not bind the dealer.
When must the assignment agreement be executed?
The assignment agreement must be executed on or before loan closing — it is a standard closing deliverable. The cap dealer’s legal team must review and sign the document, which typically takes 3–7 business days from when they receive the lender’s template. Starting this process at least 10–14 business days before your closing date is strongly recommended to avoid last-minute delays. Do not wait until the week of closing to send the template to the dealer’s legal team.
What happens to my settlement payments while the assignment is active?
While the assignment agreement is active, cap settlement payments flow directly from the dealer to the lender’s designated lockbox or restricted account — not to your bank account. The lender’s servicer then credits those settlements against your monthly interest payment, reducing the net amount you owe. You will see this reflected on your monthly loan statement as a cap settlement credit. This is the correct and expected behavior under the assignment agreement — your cap is working even though you don’t see the money in your own account.
How do I get the cap back when the loan is repaid?
Upon full repayment of the loan, the lender is obligated under the release provision of the assignment agreement to release their security interest and provide written confirmation to both you and the dealer that the assignment is terminated. You regain full control of the cap. If significant time remains on the cap term, immediately request a termination bid from the dealer — the residual market value is yours to recover as a cash payment. Larger caps with 6+ months remaining in an elevated rate environment can produce termination bids of $50,000–$200,000+.
Can I use a different cap provider’s standard form instead of my lender’s template?
You can attempt to, but it is not advisable. Most institutional lenders have reviewed and approved their own assignment agreement template — they know what provisions it contains and they are comfortable enforcing it. A dealer-drafted assignment form may contain provisions that differ from the lender’s standard or may omit language the lender considers essential. Using the lender’s template is almost always faster because the lender’s legal team has already reviewed and approved it. The dealer’s legal team is responsible for reviewing and approving the lender’s form — they cannot require you to use their form instead.
Know the Cap Terms Before the Assignment Is Drafted
The assignment agreement must reference the cap’s economic terms precisely — and those terms must match the cap confirmation exactly. The best time to confirm your deal’s cap parameters (notional, strike, term) is before either document is prepared. A five-minute calculation gives you a clear benchmark to work from and prevents discrepancies between the confirmation and the assignment that can cause lender rejection or legal complications at closing.
Use the Waldev interest rate cap calculator to model your specific deal parameters and generate an independent premium estimate. Knowing the right terms in advance means the cap confirmation and assignment agreement are drafted correctly from the first draft — saving time, reducing back-and-forth, and ensuring you arrive at closing with all documentation aligned.
