Liabilities and Provisions
The long-term liability side of the balance sheet. We start with bonds and the effective-interest method (why interest expense is not the coupon), move to leases and the IFRS 16 revolution that pulled operating leases on-balance-sheet, then defined-benefit pensions — where the discount-rate and return assumptions are powerful earnings levers — and finish with provisions and contingent liabilities, including environmental obligations.

A bond's market (effective) rate is the discount rate that equates issue proceeds to the present value of promised payments. If market rate = coupon, the bond issues at par; if market < coupon, at a premium; if market > coupon, at a discount.
Learning outcomes
- Apply the effective-interest method to premium, discount and zero-coupon bonds.
- Report bonds across the three statements and account for debt extinguishment.
- Account for leases as a lessee under IFRS 16 and US GAAP, and as a lessor.
- Distinguish defined-benefit from defined-contribution pensions and report a DB plan.
- Distinguish liabilities, provisions and contingent liabilities, and account for environmental obligations.
Bonds and the effective-interest method
Under the effective-interest method, interest expense = beginning carrying amount × market rate at issue, and the difference between expense and the coupon amortises the premium or discount so the carrying amount converges to par at maturity. Interest expense is not the coupon.
A 3-year 10% bond, face 100,000
Issued at market rates of (1) 9%, (2) 10%, (3) 11%. Trace the carrying value and interest expense.
Show solution
Discount (11%): proceeds \(=10{,}000/1.11+10{,}000/1.11^2+110{,}000/1.11^3=97{,}556\). Year 1 interest \(=97{,}556\times11\%=10{,}731\); ending BV \(=97{,}556+10{,}731-10{,}000=98{,}287\); then 99,099; then 100,000. The discount is built up over the coupon. Premium (9%): proceeds \(=102{,}531\); interest \(=102{,}531\times9\%=9{,}228\); premium amortisation \(=10{,}000-9{,}228=772\), so BV falls 102,531 → 101,759 → 100,917 → 100,000. Par (10%): proceeds = 100,000; interest = coupon = 10,000 each year; BV unchanged.
Discount BV rises to par; premium BV falls to par; par stays at 100,000Zero-coupon bonds and the debt/equity ratio
Firm A raises 10,000 via a 3-year zero-coupon bond; Firm B via a 3-year 10% coupon bond. Market rate 10%, all earnings retained. Compare the effect on debt/equity over time.
Show solution
A zero is an extreme deep-discount bond: its carrying value accretes 10,000 → 11,000 → 12,100 → 13,310, and the (non-cash) imputed interest grows each year, depressing earnings at an increasing rate. Firm B's liability stays at 10,000 and interest is a flat 1,000. Both add 10,000 to debt at issue, so the initial D/E is identical — but for the zero, debt rises and retained earnings fall as maturity approaches, so its D/E climbs over time relative to the par bond.
Same D/E at issue; the zero's D/E rises toward maturityReporting bonds and debt extinguishment
Balance sheet: bonds at historical proceeds ± cumulative amortisation. Income statement: interest expense by the effective-interest method (or, under straight-line, coupon plus even amortisation). Cash flow: interest is CFO under US GAAP, CFO or CFF under IFRS; discount-amortisation is added back to net income and premium-amortisation subtracted (both non-cash). The fair-value option splits a liability's fair-value change: the portion from the firm's own credit risk goes to OCI; the rest to profit or loss.
Retiring debt early (calling or buying it back) produces a gain or loss = cash paid − book value. Rising rates → old low-coupon debt trades below book → a gain on retirement; falling rates → a loss. We typically see losses; either way it is a transitory item to exclude from forecasts.
Leases — the IFRS 16 single model
A lease conveys the right to use an asset for a period in exchange for consideration (lessee uses and pays; lessor owns and receives). The old "operating method" kept leased assets and obligations off balance sheet and has been abandoned. IFRS 16 eliminates the operating/finance split for lessees and applies a single model (short-term <12-month and low-value leases exempt): recognise a right-of-use (ROU) asset and a lease liability, both at the present value of lease payments; then book amortisation of the ROU asset and interest on the liability separately, with principal in CFF and interest in CFO/CFF.
10-year property lease, £1,000/yr, 6%
Find the ROU asset at inception, the annual depreciation, and the year-1 interest and principal split.
Show solution
ROU asset = PV of 10 payments of 1,000 at 6% \(=\textbf{7,360}\). Straight-line depreciation \(=7{,}360/10=\textbf{736}\)/yr (asset: 7,360 → 0 over 10 years). Liability: year-1 interest \(=7{,}360\times6\%=442\); principal repaid \(=1{,}000-442=558\), so the liability falls to \(7{,}360-558=6{,}802\). Each year interest = opening balance × 6%; capital repayment = rent − interest. Versus the old operating rule (a flat 1,000 expense), IFRS 16 front-loads total expense (depreciation + interest) — so firms with mature lease portfolios saw a small income boost on transition.
ROU 7,360; depreciation 736/yr; yr-1 interest 442, principal 558US GAAP keeps the operating/finance distinction for lessees. A finance lease is identical to IFRS; an operating lease still puts an ROU asset and liability on the balance sheet, but reports a single "lease expense" (ROU amortisation = lease payment − interest, so the asset and liability stay equal) and the whole payment as CFO. Transition can be prospective, fully retrospective, or modified retrospective (adjust opening retained earnings).
The lessor side, and the evidence
Lessors still classify leases as finance or operating. In a finance lease, the lessor derecognises the asset, books a lease receivable = PV of payments (any difference is a gain/loss), and earns interest income (cash receipt CFO). In an operating lease, the lessor keeps the asset (depreciating it), and books lease revenue — no interest income, as it is not a financing.
Once operating leases came on-balance-sheet, lessees cut long-term operating leases, raised short-term ones, and increased capex — but there was no fall in performance or value, no rise in risk, no credit-rating cuts, no covenant breaches, no employment drop. Sophisticated users had always treated operating leases as off-balance-sheet debt, so transparency brought "no news"; it merely nudged managers toward more cost-efficient asset acquisition (less private-benefit off-balance-sheet financing).
Pensions: defined contribution vs defined benefit
In a defined-contribution (DC) plan the company pays an agreed amount into the plan — an expense and operating cash outflow with no further obligation; the employee bears investment and actuarial risk. In a defined-benefit (DB) plan the company promises future payments (e.g. 70% of final salary for life) and bears the investment and actuarial risk — the complicated case.
A DB plan has a liability (PV of the promised benefits, discounted at a high-quality corporate-bond yield, driven by assumptions about final salary, longevity, inflation and the discount rate) and an asset (a funded pool of investments). Each rolls forward:
Service cost is the PV of the extra benefit earned by one more year of service; interest cost = net obligation × discount rate; actuarial gains/losses arise when assumptions (turnover, mortality, retirement age, pay growth) change.
Pension reporting — IFRS vs US GAAP
IFRS: income statement takes service cost and net interest (net asset/liability × discount rate); remeasurements (actuarial gains/losses and the return on assets above imputed interest) go to OCI and are never recycled. McConnell's rationale: remeasurements are long-term fluctuations with different predictive content, so isolating them in OCI avoids masking business performance. US GAAP uses an expected return on assets (different from the discount rate), routes past-service cost and actuarial gains/losses through OCI and amortises them — i.e. it lets firms smooth pension expense.
The discount-rate and return assumptions are potent earnings levers. IFRS forces the same rate to discount the liability and impute the asset return — removing the temptation to use over-optimistic expected returns. US-GAAP evidence: firms bias assumptions downward when "hard-freezing" plans to exaggerate the burden (Comprix & Muller, 2011); use higher assumed returns before acquisitions, near earnings thresholds, and when managers exercise options (Bergstresser et al., 2006); and discretion in the discount and compensation rates is 2–3× more effective at moving earnings than the expected return (Naughton, 2019).
Liabilities, provisions and contingent liabilities
IFRS defines a liability as "a present obligation … to transfer an economic resource as a result of past events." The three escalate in uncertainty:
Liability (strict): present obligation, timing and amount certain. Accrued liability / provision: a real and present obligation whose amount and timing are estimated (a provision can later be reversed because estimation is involved). Contingent liability: conditional on events not fully under the firm's control — it is disclosed, not recognised (no present obligation, or amount unmeasurable).
Environmental liabilities
Close-down and site-restoration provisions are major for miners (e.g. Rio Tinto). Following Schneider et al. (2018): the balance sheet shows a liability (PV of future clean-up cost) and a capitalised closure asset; the income statement shows accretion expense (the liability growing as time passes) and amortisation of the asset, with adjustments for discount-rate changes and revaluations. Crucially, US GAAP offers more ways to keep these off balance sheet — an indeterminate useful life is an acceptable reason not to recognise an asset-retirement obligation, which IFRS does not allow.
Long-term liabilities are an estimation minefield. Bonds accrue by the effective-interest method, so interest expense ≠ coupon and premiums/discounts amortise to par (a zero-coupon being the extreme that lifts D/E over time); early retirement is a transitory gain/loss. IFRS 16 ended off-balance-sheet operating leases — recognising an ROU asset and lease liability — with little real-world fallout because users already saw through them. Defined-benefit pensions hinge on the discount-rate and return assumptions, which research shows are managed opportunistically; IFRS quarantines remeasurements in non-recyclable OCI while US GAAP smooths. And provisions and contingent liabilities sit on a certainty spectrum — recognised when probable and estimable, merely disclosed when contingent — with environmental obligations more easily hidden under US GAAP than IFRS.
