Debt-for-Debt Exchange: GAAP 10% Test, COD Income, and OID

A debt-for-debt exchange carries separate tax and accounting consequences that don’t always line up. On the books, the issuer applies a present-value test to decide whether the swap is an extinguishment (immediate gain or loss) or a modification (continued carrying value with adjusted terms). For federal tax, the issuer tests whether the swap produces cancellation-of-debt income, and the holder tests whether the change is significant enough to be a deemed exchange that triggers gain or loss. The two frameworks use different measurements, so an exchange can be an extinguishment for GAAP without being a taxable event for the holder, or the reverse.

What Counts as a Debt-for-Debt Exchange

The borrower issues a new debt instrument to replace an existing one held by the same creditor, and the new instrument carries different terms: a lower principal balance, a reduced rate, a longer maturity, or some combination. The classic case is a distressed issuer asking bondholders to surrender their bonds for new ones with a lower face value or coupon, because a voluntary recovery beats the uncertainty of bankruptcy. Healthy issuers also use the structure to refinance at a lower rate or push out a maturity without running cash through the transaction.

GAAP Treatment: The 10 Percent Test

The first question for the issuer’s financial statements is whether the new debt is “substantially different” from the old. ASC 470-50 answers that with a present-value comparison. Calculate the present value of the remaining cash flows under the original terms and the present value of the cash flows under the new terms, both discounted at the effective interest rate of the original debt. If they differ by 10 percent or more, the exchange is an extinguishment. Below that, it is a modification.

Extinguishment

The issuer removes the old liability from the balance sheet and records the new debt at fair value on the exchange date. The difference between the net carrying amount of the old debt (face value adjusted for any unamortized premium, discount, or issuance costs) and the fair value of the new debt is recognized as an immediate gain or loss on the income statement. It cannot be deferred or amortized. A company swapping $100 million of bonds at par for new bonds worth $85 million books a $15 million gain on the exchange date even though $85 million of debt remains outstanding.

Third-party costs associated with the new debt reduce its initial carrying value. Any unamortized issuance costs from the old debt are written off as part of the extinguishment gain or loss.

Modification

Below the 10 percent threshold, the old liability stays on the books. The issuer adjusts the effective interest rate prospectively and recognizes no gain or loss on the exchange date. Fees paid directly to the lender reduce the carrying amount of the debt, functioning as a premium or discount adjustment. Fees paid to third parties (legal, advisory) are capitalized as debt issuance costs and amortized as an interest-expense adjustment over the remaining life of the modified instrument.

Cancellation-of-Debt Income for the Issuer

The federal tax rules ignore the GAAP framework entirely. Under Section 108(e)(10), a debtor that issues a new instrument to satisfy an existing debt is treated as having paid cash equal to the issue price of the new instrument. If that issue price is less than the adjusted issue price of the old debt, the difference is cancellation-of-debt (COD) income taxable as ordinary gross income.¹

Getting the issue price right is the most important step, and the rule shifts with trading status:

If the new debt is publicly traded, the issue price is its fair market value on the exchange date.
If the new debt is not publicly traded but the old debt is, the issue price is the fair market value of the old debt surrendered.
If neither trades publicly, the issue price is determined under the imputed interest rules of Section 1274, or defaults to the stated redemption price at maturity reduced by amounts treated as interest.²

A company with $100 million of outstanding bonds (adjusted issue price of $100 million) that exchanges them for new publicly traded bonds worth $82 million recognizes $18 million of COD income.¹

Exclusions Under Section 108

COD income is taxable unless a statutory exclusion applies. Two matter most in corporate exchanges:

Title 11 bankruptcy. If the discharge occurs in a bankruptcy case in which the court has jurisdiction over the debtor, the full amount of COD income is excluded.¹
Insolvency. A debtor whose liabilities exceed the fair market value of its assets immediately before the discharge can exclude COD income up to the amount of that insolvency. A company $15 million insolvent that realizes $20 million of COD income excludes $15 million and recognizes $5 million.³

Attribute Reduction

Excluded COD income comes with a mandatory reduction of tax attributes, which defers the tax rather than eliminating it. The prescribed order is:

Net operating losses (dollar for dollar)
General business credit carryovers (33⅓ cents per dollar)
Minimum tax credits (33⅓ cents per dollar)
Capital loss carryovers (dollar for dollar)
Basis of property (dollar for dollar)
Passive activity loss and credit carryovers
Foreign tax credit carryovers (33⅓ cents per dollar)

The taxpayer can elect to skip the ordering rule and reduce basis in depreciable property first, which is sometimes preferable when preserving NOLs matters more than preserving asset basis.⁴ The election is made on a timely filed return, with a six-month extension available for late elections filed with the notation “Filed pursuant to section 301.9100-2.”⁵

OID Deductions and the AHYDO Trap

When the new debt’s stated redemption price at maturity exceeds its issue price, the excess is original issue discount.⁶ The issuer deducts OID over the life of the instrument using the constant-yield method, which front-loads more of the deduction into later years as the adjusted issue price grows. In a distressed swap where new bonds are issued at a steep discount, the deduction can partially offset the COD income.

The trap is the applicable high yield discount obligation (AHYDO) rule. A debt instrument is an AHYDO when maturity exceeds five years, yield to maturity equals or exceeds the applicable federal rate plus five percentage points, and the instrument has significant OID.⁷ The “disqualified portion” of the OID on an AHYDO is permanently nondeductible, and the remaining OID is deductible only when actually paid. Distressed exchanges create AHYDO risk because the low issue price inflates the yield, making the AFR-plus-five threshold easy to cross. Modeling this before closing avoids a permanent lost deduction.

Holder Consequences: Significant Modification

For the holder, the question is whether the exchange is a “significant modification” under Treasury Regulation 1.1001-3. If it is, the holder is treated as disposing of the old instrument and receiving the new one, with immediate gain or loss.⁸ The regulation tests categories of changes independently:

Yield. A change is significant if it varies from the original yield by more than the greater of 25 basis points or 5 percent of the original yield. An 8 percent bond needs a change exceeding 40 basis points to cross the threshold.
Payment timing. A deferral is significant if it is material based on facts and circumstances. A safe harbor protects deferrals where all postponed payments are unconditionally payable within the lesser of five years or 50 percent of the original term.
Collateral and guarantees. For recourse debt, changes are significant only if they change payment expectations. For nonrecourse debt, any release, substitution, or alteration of a substantial amount of collateral is significant, though swapping fungible collateral like government securities is not.⁸

Failing any one test makes the modification significant. Multiple small changes that individually fall below their thresholds can be tested in the aggregate when they occur together.

Gain, Loss, and Character

On a significant modification, the holder’s gain or loss equals the fair market value of the new debt received minus the adjusted basis in the old debt. A holder that bought the original bonds at a discount in the secondary market can end up with a sizable taxable gain even when the new bonds are worth less than par.

The character is generally capital if the debt was held as a capital asset, but accrued market discount is recaptured as ordinary. Under Section 1276, gain on the disposition of a market discount bond is ordinary income to the extent of accrued market discount, and the statute treats that ordinary income as interest for most purposes.⁹ This catches holders who bought distressed debt cheaply and then participated in an exchange at a higher recovery value.

If the modification is not significant, no realization event occurs. The holder keeps its existing basis and holding period in the modified instrument.

OID Accrual on the New Instrument

When the deemed exchange creates new debt with OID, the holder includes that OID in gross income annually over the life of the instrument, regardless of whether cash interest is received. The accrual uses the constant-yield method, applied to the adjusted issue price at the start of each accrual period.¹⁰ Each year’s OID inclusion increases the holder’s basis, reducing future gain or increasing future loss on ultimate sale or redemption. A zero-coupon bond received in an exchange produces no cash interest but generates phantom income every year. Planning for that cash mismatch matters before agreeing to the exchange terms.

Reporting

An issuer excluding COD income under any provision of Section 108 files Form 982 (Reduction of Tax Attributes Due to Discharge of Indebtedness) with its federal return for the year of discharge. Part I identifies the exclusion; Part II reports the required attribute reduction in the prescribed order.⁵ Missing the form doesn’t automatically forfeit the exclusion, but it invites scrutiny.

A lender or financial institution that cancels $600 or more of debt files Form 1099-C.¹¹ In a bond exchange, this obligation typically falls on the original creditor rather than the issuer, but intercompany and bank-debt restructurings can put both roles inside the same entity.

Holders recognizing gain or loss report it on the schedule for their entity type and pick up OID accruals annually as interest income. Keep documentation of basis in the old debt, the fair market value determination on the exchange date, and any accrued market discount calculations. The IRS has no independent record of those figures, and the burden of proof sits with the taxpayer.

Why Book and Tax Answers Diverge

The GAAP 10 percent test uses a present-value comparison at the original effective interest rate. The tax significant-modification tests examine yield changes, payment timing, and collateral through separate lenses with their own thresholds. An exchange that is an extinguishment for book purposes may not be a significant modification for tax, and the reverse also happens. The mismatch creates temporary book-tax differences that must be tracked and unwound over the remaining life of the instrument through deferred tax accounting under ASC 740. Modeling both outcomes before executing the exchange avoids expensive cleanup later.
