A troubled debt restructuring happens when a creditor grants a concession to a borrower in financial difficulty, agreeing to terms it would not accept from a healthy borrower. Two conditions have to be present at the same time: the borrower is genuinely struggling, and the creditor gives up something of economic value because of that struggle. Miss either one and the modification is an ordinary loan workout with ordinary accounting. For most U.S. reporting entities the formal TDR classification ended in 2023 when FASB’s ASU 2022-02 took effect, but the economics still drive bank examinations, tax reporting, and the books of entities that have not yet adopted the current expected credit loss model.
The Two Conditions That Define a TDR
Under ASC 310-40 (for creditors) and ASC 470-60 (for debtors), both conditions had to be true simultaneously.
Borrower Financial Difficulty
The borrower did not need to be in active default. The creditor could reach the financial-difficulty conclusion if it was probable the borrower would default on any of its debts in the foreseeable future absent the modification.1Financial Accounting Standards Board (FASB). Accounting Standards Update No. 2011-02 – A Creditors Determination of Whether a Restructuring Is a Troubled Debt Restructuring Common indicators were a borrower who could not meet obligations as they came due, was hunting for emergency capital, was selling off assets to cover existing debts, or had filed for bankruptcy protection. The call was a judgment one, and the creditor had to document the evidence.
A Concession by the Creditor
The creditor had to give the borrower something it would not give a borrower in good standing. The classic test: if the restructured loan’s effective interest rate fell below the current market rate for a comparable new loan, a concession existed.2Community Banking Connections. Saying Goodbye to Troubled Debt Restructurings No concession existed if the borrower could have obtained the same terms from a third-party lender, because the borrower’s financial difficulty was not driving the modification. The creditor had to accept an outcome that was financially worse than collecting the original loan in full or pursuing immediate foreclosure.3Federal Deposit Insurance Corporation.

Forms the Concession Could Take
Creditors usually combined more than one of the following in a single restructuring:
- Interest rate reduction for the remaining term, cutting total interest collected over time.
- Maturity extension, often paired with a lower rate, to ease monthly payments.
- Principal forgiveness, writing off part of the face amount owed and creating an immediate gain for the borrower and loss for the creditor.
- Debt-for-asset swap, in which the borrower surrenders property or other non-cash assets at fair value to settle part or all of the debt.
Not every change to a troubled borrower’s loan qualified. A standalone covenant waiver, for instance, might not involve enough economic sacrifice to count. The question was always whether the creditor gave up measurable value because of the borrower’s financial problems.2Community Banking Connections. Saying Goodbye to Troubled Debt Restructurings
How the Debtor Records a TDR
Everything on the debtor’s side turns on one comparison: total future cash payments under the modified terms, undiscounted, against the loan’s current carrying amount (principal plus accrued interest).
Future Payments Below the Carrying Amount
If undiscounted future payments are less than the carrying amount, the debtor recognizes a gain equal to the difference. On a loan with a $1.2 million carrying amount and restructured terms calling for $1.0 million in total future payments, the debtor records a $200,000 gain. The carrying amount is written down to match the total future payments, every subsequent payment reduces principal, and no interest expense is recognized for the rest of the loan’s life.
Future Payments Equal to or Above the Carrying Amount
If undiscounted future payments equal or exceed the carrying amount, no gain is recognized and the carrying amount stays put. The excess becomes total interest expense over the remaining term. The debtor computes a new effective interest rate that equates the present value of all future payments to the current carrying amount and applies that rate each period.
The split matters. In the first case the income statement gets an immediate lift; in the second the benefit shows up gradually through lower interest expense. Getting the comparison wrong misstates income in the period of restructuring.
How the Creditor Records a TDR
The creditor’s side works differently. Rather than undiscounted cash flows, the creditor measures impairment at the present value of expected future cash flows under the modified terms, discounted at the loan’s original effective interest rate.3Federal Deposit Insurance Corporation. Interagency Supervisory Guidance Addressing Certain Issues Related to Troubled Debt Restructurings
Using the original rate rather than the restructured rate is deliberate. It isolates the economic loss caused by the concession; applying the new, lower rate would mask it. The gap between the loan’s recorded investment and that present value is the impairment loss, recognized immediately on the income statement and typically charged against the allowance for loan losses.
When a restructuring involves a debt-for-asset swap, the creditor records the asset received at current fair value. A $500,000 loan balance settled by property worth $450,000 produces a $50,000 loss on the creditor’s books.
Tax Consequences of Forgiven Debt
The accounting rules above sit in financial statements. Tax is a separate system, and it catches borrowers off guard regularly.
Cancellation of Debt Income
Under federal tax law, debt a creditor forgives generally counts as gross income to the borrower.4Internal Revenue Service. Revenue Ruling 2012-14 – Income from Discharge of Indebtedness If a creditor cancels $600 or more, it must file Form 1099-C reporting the amount to both the borrower and the IRS.5Internal Revenue Service. Instructions for Forms 1099-A and 1099-C Financial institutions, credit unions, government agencies, and any organization whose significant business activity is lending money all fall under the filing requirement.
A borrower who gets $200,000 in principal forgiven in a restructuring will receive a 1099-C for that amount and, absent an exclusion, owes tax on it as ordinary income. The relief on the loan can arrive with an unwelcome tax bill.
Section 108 Exclusions
Section 108 of the Internal Revenue Code shelters cancelled debt from tax in several situations:
- Bankruptcy. Debt discharged in a Title 11 case is fully excluded from income, and this exclusion takes priority over the others.6Office of the Law Revision Counsel. 26 USC 108 – Income From Discharge of Indebtedness
- Insolvency. If total liabilities exceed the fair market value of total assets immediately before the discharge, the cancelled amount is excluded up to the amount of insolvency. A borrower with $800,000 in liabilities and $700,000 in assets is insolvent by $100,000, so only $100,000 of forgiven debt can be excluded under this provision.7Internal Revenue Service. What if I Am Insolvent?
- Qualified farm indebtedness, which has its own exclusion for certain agricultural debts.
- Qualified real property business indebtedness, which can cover debt secured by real property used in a trade or business, though not for C corporations.6Office of the Law Revision Counsel. 26 USC 108 – Income From Discharge of Indebtedness
These exclusions have a cost. In exchange, the borrower must reduce tax attributes in a prescribed order: net operating losses first, then general business credits, capital losses, property basis, passive activity losses, and foreign tax credit carryovers. Both the exclusion and the attribute reduction are reported on Form 982.8Internal Revenue Service. Instructions for Form 982 – Reduction of Tax Attributes Due to Discharge of Indebtedness
The Creditor’s Side
Any uncollectible portion of a restructured loan may qualify as a bad debt deduction for the creditor. For business bad debts, the creditor can deduct the loss in full or in part once it determines the debt is partially or wholly worthless, in the year the debt becomes worthless, and only after showing reasonable collection efforts.9Internal Revenue Service. Topic No. 453 – Bad Debt Deduction
Why the TDR Label Mostly Ended in 2023
On March 31, 2022, FASB issued ASU 2022-02, which eliminated the TDR recognition and measurement guidance in ASC 310-40 for entities that had adopted the Current Expected Credit Losses (CECL) model.10Financial Accounting Standards Board (FASB). Accounting Standards Update No. 2022-02 FASB’s reasoning: stakeholders found TDR analysis costly and complex, while CECL already captured expected losses on a lifetime basis, so the incremental effect of a TDR label on the allowance was usually insignificant.
For CECL adopters, ASU 2022-02 became effective for fiscal years beginning after December 15, 2022. For entities that had not yet adopted CECL, the amendments took effect when they did. One practical change: creditors that use a discounted cash flow method to estimate their credit loss allowance must now use the post-modification contractual interest rate rather than the original effective rate when measuring losses on restructured loans. That reverses the old TDR approach, which required the original rate to isolate the concession’s cost.10Financial Accounting Standards Board (FASB). Accounting Standards Update No. 2022-02
Transparency did not disappear with the label. ASU 2022-02 replaced the old TDR disclosures with enhanced requirements focused on modifications made to borrowers experiencing financial difficulty, covering the type of modification, its financial effect, and how the borrower performed in the 12 months after. If a borrower defaults within those 12 months, the creditor must separately disclose the type of modification and the defaulted amount.
Where the TDR Concept Still Matters
Even after the accounting label went away, the underlying analysis still shows up in three places.
Tax reporting is unchanged. Cancellation of debt income, 1099-C filing, and the Section 108 exclusions all run on their own statutory framework and were not touched by ASU 2022-02.
Bank examinations continue to focus on troubled modifications. The FDIC’s interagency guidance states that a TDR designation for accounting purposes does not automatically result in an adverse loan classification, and that a modified loan adversely classified at the time of restructuring need not stay that way if the borrower improves.11Federal Deposit Insurance Corporation. Troubled Debt Restructurings Interagency Supervisory Guidance Examiners look at whether the modification rests on a realistic assessment of the borrower’s ability to perform under the new terms, whether the bank documented its analysis, and whether the allowance for credit losses reflects the modification’s true risk.
And the historical TDR framework still governs the books of any entity that has not yet adopted CECL. For those creditors and debtors, both conditions, the measurement rules, and the disclosure requirements described above remain in force until adoption.
