Long-term debt II: notes, extinguishment, modifications and presentation

Lesson 3 followed a bond from issue to maturity. Real debt rarely behaves so neatly. Companies borrow from banks on installment notes, repay bonds early when interest rates fall, renegotiate loans when they run into trouble, breach covenants, and issue debt that converts into shares. This lesson covers those events: installment and mortgage notes, early extinguishment, modifications and troubled debt restructurings, the fair value option, convertible debt and the classification questions raised by covenants. The framework differences here are larger than for plain bonds, so the IFRS and US GAAP treatments are set side by side.

Installment notes and mortgages

Many long-term notes are repaid in equal installments that combine interest and principal, like a home mortgage. The payment is the annuity that amortizes the principal at the stated rate. Each payment is split: interest is the opening balance times the rate, and the rest reduces principal. Early payments are mostly interest; later payments are mostly principal. Only the principal due within twelve months is a current liability.

Mortgages are installment notes secured by real property; the lender can take the property if the borrower defaults. Their accounting is the same, with additional disclosure of the assets pledged as security. Canadian residential mortgages compound interest semi-annually under the Interest Act, so the monthly rate is derived from the semi-annual rate (FIN-201 lesson 4); commercial loans usually compound monthly.

Extinguishing debt before maturity

A company may repay debt early by exercising a call option in the indenture, buying its bonds in the open market or refinancing through a new issue. When debt is extinguished, the difference between the reacquisition price (including any call premium and transaction costs) and the carrying amount of the debt, including unamortized discount, premium and issue costs, is recognized as a gain or loss in profit or loss. Because the carrying amount and the price rarely match, extinguishments often produce gains or losses that analysts treat as non-recurring.

Under ASC 405-20 a liability is derecognized when the debtor pays the creditor or is legally released. ASC 470-50 requires the gain or loss to be recognized in income; since ASU 2015-01 eliminated extraordinary items, it is presented within income from continuing operations, often as a separate line.

Modifications and exchanges of debt

Instead of repaying debt, a borrower and lender may change its terms: a lower interest rate, a longer maturity, a reduced principal or added fees. The question is whether the change is so substantial that the old debt should be treated as extinguished and new debt recognized, or whether the old debt continues with modified terms. Both frameworks use a quantitative '10 percent test': compare the present value of the cash flows under the new terms, including fees paid net of fees received, discounted at the original effective interest rate, with the present value of the remaining cash flows of the original debt (its carrying amount). If the difference is at least 10 percent, the modification is substantial and treated as an extinguishment.

If the modification is not substantial, ASC 470-50 does not recognize a gain or loss. Instead, the existing carrying amount (adjusted for fees paid to the lender) continues, and a new effective interest rate is computed that equates the revised cash flows with that carrying amount, so the effect is spread over the remaining term. This is a well-known difference from IFRS 9, which recognizes the effect at once. Third-party costs are expensed in a modification and capitalized in an extinguishment, the reverse of fees paid to the lender.

# The 10% test and accounting for a modified bank loan
original_eir = 0.06
carrying = 5_000_000                    # 6% loan, 3 years left, interest annual
def pv(flows, r):
    return sum(cf / (1 + r) ** t for t, cf in enumerate(flows, start=1))

# New terms: rate cut to 4%, maturity extended to 5 years, $100,000 fee paid to the lender
new_flows = [200_000] * 4 + [5_200_000]
fee_paid = 100_000
pv_new = pv(new_flows, original_eir) + fee_paid
change = (carrying - pv_new) / carrying
print(f"PV of new flows plus fee at 6%: {pv_new:,.0f}")
print(f"Difference from carrying amount: {change:.1%} -> {'extinguishment' if abs(change) >= 0.10 else 'modification'}")

# IFRS 9: remeasure at the original EIR, recognize a gain; fee adjusts the carrying amount
remeasured = pv(new_flows, original_eir)
print(f"IFRS 9 gain on modification: {carrying - remeasured:,.0f}; new carrying {remeasured - fee_paid:,.0f}")

# US GAAP (ASC 470-50): no gain; solve a new effective rate on carrying less the fee
target = carrying - fee_paid
lo, hi = 0.0, 0.2
for _ in range(100):
    mid = (lo + hi) / 2
    lo, hi = (mid, hi) if pv(new_flows, mid) > target else (lo, mid)
print(f"ASC 470-50: no gain; carrying {target:,.0f}; new effective rate {mid:.3%}")

PV of new flows plus fee at 6%: 4,678,764
Difference from carrying amount: 6.4% -> modification
IFRS 9 gain on modification: 421,236; new carrying 4,478,764
ASC 470-50: no gain; carrying 4,900,000; new effective rate 4.455%

The rate cut and extension reduce the present value of the loan by 6.4 percent, under the 10 percent threshold, so the debt is modified rather than extinguished. Under IFRS 9 Northlake recognizes a modification gain of $421,236 immediately and continues to recognize interest at the original 6 percent on the lower carrying amount. Under US GAAP no gain is recognized; the carrying amount, reduced by the fee, becomes $4.9 million, and interest is recognized at a new effective rate of about 4.46 percent for the next five years. Over the life of the loan the total effect is the same; only the timing differs.

For debtors, ASC 470-60 still contains a separate model for troubled debt restructurings: when the creditor grants a concession because the debtor is in difficulty, the debtor recognizes a gain only if the total future undiscounted cash flows under the new terms are less than the carrying amount. Otherwise, a new effective rate is computed prospectively. (ASU 2022-02 eliminated the TDR model for creditors, not debtors.) Transfers of assets or equity in full settlement produce a gain measured against the fair value of what is given up.

The fair value option

ASC 825-10 allows an entity to elect the fair value option for eligible financial liabilities on an instrument-by-instrument basis at initial recognition. Changes in fair value are recognized in net income, except the portion attributable to instrument-specific credit risk, which ASU 2016-01 requires to be presented in other comprehensive income. Debt issuance costs on liabilities at fair value are expensed as incurred.

Convertible debt

Since ASU 2020-06, effective for public business entities in 2022 and others in 2024, most convertible debt is accounted for as a single liability at amortized cost under ASC 470-20, with no separation of the conversion feature, unless the feature must be bifurcated as a derivative under ASC 815 or the debt was issued at a substantial premium. Interest expense is therefore close to the cash coupon. IFRS reporters split the same instrument into a liability and an equity component, so they report higher interest expense on convertible debt than US GAAP reporters.

Covenants, breaches and classification

Under ASC 470-10, debt that is callable because of a covenant violation at the balance sheet date is classified as current unless the creditor has waived or lost the right to demand repayment for more than one year from the balance sheet date, or the debt agreement contains a grace period within which the violation is probable of being cured. A waiver obtained after the balance sheet date but before the statements are issued can support non-current classification, unlike under IFRS. Subjective acceleration clauses require disclosure, and classification as current if acceleration is probable.

Because the classification of debt can swing a current ratio dramatically, readers should study the notes on covenants and waivers, especially for companies near their limits. A reclassification of a large loan to current is often an early warning of financial distress, and auditors consider it carefully when assessing whether the going-concern basis is appropriate.
