How to Account for an Interest Rate Collar — a Combination of a Purchased Cap and a Written Floor — as a Cash Flow Hedge of Variable-Rate Debt
Recording an interest rate collar (cap + floor) that limits both the maximum and minimum interest cost on floating-rate debt — designated as a single cash flow hedging instrument with the effective portion deferred in OCI.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Interest Rate Cap — Fair Value Asset Component | Asset (+) | 3,800,000.00 | - |
| Interest Rate Floor — Fair Value Liability Component (Written) | Liability (+) | - | 2,200,000.00 |
| OCI — Net Collar FV Change (Effective Portion of Cash Flow Hedge) | OCI (+) | - | 1,600,000.00 |
| Interest Expense (Reclassified from OCI When Hedged SOFR Payment Occurs) | Expense (+) | 850,000.00 | - |
| OCI — Collar Reclassification to Interest Expense | OCI (-) | - | 850,000.00 |
💡 Accountant's Note
An interest rate collar combines a purchased cap (protection against rates rising above the cap strike) and a written floor (obligation to make payments if rates fall below the floor strike). The collar limits the effective interest rate range: the company pays no more than the cap rate and benefits from rates down to the floor rate. The net premium is the difference between the cap premium and the floor premium received — a zero-cost collar has equal premiums. Both components are evaluated together for hedge effectiveness and designated as a single hedging instrument. When SOFR is between the floor and cap strikes, neither option settles and the effective interest rate equals SOFR.
Practitioner & Systems Framework
💻 ERP Architecture
Track the cap and floor components separately in the derivatives module (each has its own FV) but designate and test them as a single combined collar. The combined FV is the net of the cap FV (asset when cap in-the-money or rates rose) and floor FV (liability when floor in-the-money or rates fell significantly). The net collar FV drives the OCI change. When the cap settles (SOFR exceeds cap strike): receive cash, reclassify from OCI to interest expense (offsetting the higher SOFR payment). When the floor settles (SOFR falls below floor strike): pay cash, reclassify from OCI to interest expense (offsetting the lower SOFR benefit).
⚠️ Audit Flags
Auditors evaluate the collar as a combined instrument for effectiveness purposes. If the cap and floor are with different counterparties or under different ISDA agreements, they may not qualify as a single hedging instrument — each must be separately designated. The written floor creates a maximum benefit from rate declines — if rates fall dramatically, the floor obligation can be significant. Auditors test: (1) the combined FV at period-end (both legs independently valued), (2) whether the collar's combined fair value response closely tracks the hedged variable-rate debt's interest cost variability, (3) the OCI reclassification timing matches the SOFR interest payment dates.
📄 Required Documentation
Collar confirmation (cap and floor terms, strikes, notional, maturity, whether same counterparty and ISDA), cap FV and floor FV at each period-end (independent pricing), net collar FV calculation, OCI rollforward by hedge relationship, cap and floor settlement records (cash received and paid), interest expense reclassification schedule (matching SOFR payment dates), combined effectiveness test (treating cap + floor as one instrument).
