1 · Revenue Recognition
Revenue is recognised in the period it is earned — not necessarily when cash is collected. The converged IFRS 15 / ASC 606 standard (effective 2018) uses a single five-step model applicable to virtually all revenue-generating contracts.
Core principle of converged standards (IFRS 15 / ASC 606): Revenue should be recognised to "depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services."
An agreement with commercial substance where collectability is probable. IFRS: "more likely than not." US GAAP: "likely to occur." Same wording, different thresholds → may treat similar contracts differently.
Each distinct good or service (or bundle) in the contract is a separate performance obligation. "Distinct" = customer can benefit from it alone OR combined with readily available resources, AND it can be separated from other promises in the contract.
What the seller estimates it will receive. Includes variable consideration (refunds, discounts, rebates). Recognise only to the extent it is highly probable that revenue will NOT be subsequently reversed.
Allocate the total transaction price to each identified performance obligation based on relative standalone selling prices. Addresses amounts recognised per obligation.
Revenue is recognised when control of the good or service transfers to the customer — either at a point in time or over time. Addresses timing of recognition. Control indicators: right to payment, legal title, physical possession, significant risks and rewards, customer acceptance.
Scenario | Recognition Treatment | Balance Sheet Impact |
|---|---|---|
Cash received before delivery (advance payment) | Record contract liability (deferred/unearned revenue); recognise revenue as delivered | Liability until performance complete |
Revenue earned but payment conditional on future event | Record contract asset (not a receivable yet) | Asset until unconditional right to payment |
Revenue earned, unconditional right to payment | Record accounts receivable; recognise revenue immediately | Receivable on balance sheet |
Principal vs Agent (e.g., MegaDigital) | Principal: gross revenue. Agent: net commission only. | Dramatically different revenue, same net profit |
Franchise royalties (e.g., Mahjong Pizza) | Royalty % of franchisee sales recognised as revenue; upfront fees deferred and amortised over franchise term | Deferred revenue liability for upfront fees |
SaaS subscription (e.g., CReaM Software) | Recognised over subscription period (performance obligation over time) | Contract liability reduces as service delivered |
Principal vs agent — major margin impact: as principal (MegaDigital example): Revenue = USD100, COGS = USD70, GP = 30%. As agent: Revenue = USD30 (commission only), COGS = USD0, GP = 100%. Same net profit (USD20), but dramatically different revenue and margin ratios. Critical for e-commerce companies where the mix of principal/agent sales changes over time.
Analyst implications: identify differences in revenue recognition methods; adjust where possible; characterise policies as more or less conservative. Conservative revenue recognition (defer when uncertain) → better earnings quality than aggressive (accelerate recognition).
Disclosure requirements (IFRS 15): contracts with customers, revenue disaggregated by nature/geography/timing; significant judgments and estimates; remaining performance obligations and transaction price allocated to those obligations.
2 · Expense Recognition & Capitalisation vs Expensing
Expenses are recognised when the company consumes economic benefits or loses previously recognised economic benefits. Three core models apply:
Three expense recognition models:
1. Matching principle — expenses recognised in the same period as the associated revenue (e.g., COGS matched against sales revenue)
2. Period costs / as incurred — administrative, IT, R&D, maintenance costs — expensed when the cost occurs
3. Capitalisation + depreciation/amortisation — long-lived assets capitalised on balance sheet, then systematically expensed over useful life
Asset recorded on balance sheet. Appears as investing outflow on cash flow statement. Income Statement: lower expense in Year 1 (only depreciation, not full cost). Balance Sheet: higher asset. Over time: same total expense, but spread across useful life. Boosts early profitability; depresses later years.
Full cost hits income statement in Year 1. Higher expense in Year 1 → lower net income and taxes. Cash flow same (both are investing outflows initially). More conservative approach. Later years have HIGHER income (no depreciation). Income stream is more volatile.
EUR900 equipment, 3-year life, EUR1,500 revenue/year, EUR500 other cash costs/year
Tax rate: 30%; same method for tax and financial reporting
CAP Inc (EUR900 capitalised, EUR300/yr depreciation):
Year 1-3: Revenue 1,500 − Expenses 500 − Dep 300 = EBIT 700, Tax 210, Net 490
NOW Inc (EUR900 expensed in Year 1):
Year 1: Revenue 1,500 − Cash exp 1,400 − Dep 0 = EBIT 100, Tax 30, Net 70
Year 2-3: Revenue 1,500 − Cash exp 500 = EBIT 1,000, Tax 300, Net 700
Key: CAP has higher Year 1 income; NOW has higher Year 2-3 income.
Total 3-year income is the SAME for both (only timing differs).
Depreciation method choices affect comparability: straight-line vs accelerated (double-declining, units of production). Accelerated methods → higher early depreciation → lower early income → but higher later income. Same total depreciation over the asset's life.
Key estimates affecting income: depreciation method, estimated useful life, estimated salvage value, uncollectible accounts (bad debt provision), warranty expense estimates. All require management judgment and can be more or less conservative.
Interest costs — capitalisation: both IFRS and US GAAP require capitalisation of interest on borrowings directly attributable to acquiring/constructing qualifying assets. Capitalisation → lower interest expense (income statement) but higher assets (balance sheet); later reversed through higher depreciation.
Internal development costs: US GAAP: expense all R&D immediately (except certain software development costs). IFRS: expense research phase; capitalise development phase costs if technical feasibility and intent to complete can be demonstrated. IFRS allows more asset recognition → higher assets, lower early expenses.
AMRC case study lesson: depreciation method choices (straight-line vs accelerated), useful life estimates, and capitalisation decisions (e.g., expensing printer vs capitalising it) create significant differences in reported profitability between companies even with identical underlying economics.
3 · Non-Recurring Items & Accounting Changes
To forecast future earnings, separate items likely to continue from those that are not. Disclosure practices help analysts assess recurrence.
Reported in Continuing Operations
Restructuring charges, gains/losses on asset sales, impairment charges. Presented separately within continuing operations (IFRS: separate line; US GAAP: separately disclosed). Analysts assess likelihood of recurrence. Danone example: "Other operating income (expense)" shows capital gains, legal settlements, integration costs.
Reported Separately, Net of Tax
Results of a component being sold/disposed with no further involvement. Both IFRS and US GAAP: reported at bottom of income statement, net of tax, including per-share basis. Assets/liabilities reclassified as "held for sale." Analysts typically exclude from future earnings forecasts once disposal is complete.
Retrospective Application (Restate Prior Periods)
Requires restating prior period financial statements as if new policy always applied ("full retrospective"). Makes statements comparable. Microsoft 2018 example: revenue recognition change added USD6.6B to 2017 revenue. Modified retrospective: only adjust opening retained earnings (no prior restatement).
Prospective Only (No Restatement)
Changes in useful life, salvage value, bad debt estimates, pension assumptions. Applied going forward only — no prior period adjustment. Disclosed in notes. Catalent example: changing pension discount rate methodology applied prospectively from June 30, 2016.
Error corrections — handled by full retrospective restatement (including balance sheet, equity statement, and cash flows). Unlike accounting changes, error corrections cannot use a prospective approach. Required disclosures about errors may reveal weaknesses in internal controls.
Policy vs estimate change — the critical distinction: accounting policy changes = retrospective; estimate changes = prospective. A change in depreciation method is a policy change (retrospective). A change in an asset's useful life estimate is an estimate change (prospective).
Changes in scope and exchange rates: acquisitions consolidated from closing date → comparability affected. Exchange rate changes → affect multinational revenues. Neither requires disclosure of the specific line-item effects, though most companies provide summary information in MD&A.
4 · Earnings Per Share (EPS)
Simple capital structure = no potentially dilutive securities → Basic EPS = Diluted EPS. Complex capital structure = has convertible bonds, convertible preferred, options, or warrants → must report both Basic and Diluted EPS.
Basic EPS = (Net income − Preferred dividends) / Weighted average shares
Weighted average: each quantity of shares × fraction of year outstanding
Stock splits / stock dividends: treated retroactively to beginning of period
Examples:
Shopalot: USD1,950,000 / 1,500,000 = USD1.30
Angler (with preferred div): (2,500,000 − 200,000) / 1,125,000 = USD2.04
Angler + 2-for-1 split: (2,500,000 − 200,000) / 2,250,000 = USD1.02
Assume convertible preferred converted at beginning of period:
Numerator: Net income (add back preferred dividends — not paid if converted)
Denominator: Weighted avg shares + new shares from conversion
Bright-Warm example: 20,000 pref shares × 5 common per share = 100,000 new shares
Basic: (1,750,000 − 200,000) / 500,000 = USD3.10
Diluted: 1,750,000 / 600,000 = USD2.92
Assume convertible debt converted at beginning of period:
Numerator: Net income + after-tax interest saved (interest × (1 − tax rate))
Denominator: Weighted avg shares + new shares from conversion
Oppnox example: USD50,000 @ 6%, tax 30%, converts to 10,000 shares
After-tax interest = USD3,000 × 0.70 = USD2,100
Basic: 750,000 / 690,000 = USD1.09
Diluted: (750,000 + 2,100) / 700,000 = USD1.07
Assume options exercised → cash received → repurchase shares at avg market price
Numerator: unchanged (no income effect from options)
Denominator: Weighted avg shares + incremental net shares issued
Incremental shares = shares issued on exercise − shares repurchased with proceeds
Hihotech: 30,000 options @ USD35, avg price USD55
Proceeds = 30,000 × 35 = USD1,050,000
Repurchased = 1,050,000 / 55 = 19,091 shares
Incremental = 30,000 − 19,091 = 10,909 net new shares
Basic: 2,300,000 / 800,000 = USD2.88
Diluted: 2,300,000 / 810,909 = USD2.84
Antidilutive securities: if including a security would increase (not decrease) EPS, it is antidilutive and excluded from diluted EPS. Diluted EPS ≤ Basic EPS always. Dim-Cool example: 20,000 convertible preferred × 3 shares each = 60,000 new shares. If-converted EPS = USD3.13 > Basic USD3.10 → antidilutive → Diluted EPS = Basic EPS = USD3.10.
IFRS uses "inferred shares" for options (same arithmetic as US GAAP treasury stock method, different terminology). Proceeds assumed received from issuance of new shares at market price → "inferred" shares disregarded → net incremental shares same result.
EPS from continuing operations must be disclosed separately from total EPS. Both basic and diluted must be disclosed. AB InBev example: Basic from continuing operations USD4.04; Diluted from continuing operations USD3.96.
Changes in EPS result from: (1) changes in net income, (2) changes in weighted average shares (buybacks decrease, issuances increase), or (3) both. AB InBev's 2016→2017 EPS improvement was driven by net income increase despite higher share count.
5 · Common-Size Analysis & Income Statement Ratios
Common-size analysis expresses each income statement line item as a percentage of revenue. This removes the effect of absolute size and enables time-series and cross-sectional comparison.
Company | Sales | Gross Profit | Gross Margin | Operating Profit | Operating Margin |
|---|---|---|---|---|---|
Company A (USD10M) | USD10M | USD7M | 70% | USD2M | 20% |
Company B (USD10M) | USD10M | USD2.5M | 25% | USD1.5M | 15% |
Company C (USD2M) | USD2M | USD1.4M | 70% | USD0.4M | 20% |
What common-size reveals: Company C appears smallest in absolute terms (USD0.4M profit vs USD1.5M for B), but its 20% operating margin equals Company A's and exceeds Company B's 15%. Companies A and C have same gross margin (70%) vs B's 25% — A and C likely sell differentiated/premium products. Company B may be a low-cost competitor who offsets lower margins by cutting R&D and advertising.
Gross profit margin = Gross profit / Revenue
Operating profit margin = Operating profit (EBIT) / Revenue
Pretax margin = Profit before tax / Revenue
Net profit margin = Net income / Revenue
AB InBev 2017: Revenue USD56,444M · GP USD35,058M · GP margin = 62.1%
Operating profit USD17,152M · Operating margin = 30.4%
Profit from continuing operations USD9,155M · Net margin = 16.2%
Note: taxes vs pretax income (not vs revenue) — use effective tax rate analysis.
S&P 500 sector medians vary widely: IT gross margin 62.4% vs Energy 37.7%
Taxes in common-size: for taxes, compare tax expense to pretax income (the effective tax rate), not to revenue. Effective tax rate = income tax expense / pretax income. Variations in effective tax rates reveal tax planning differences and special items.
Projecting future net income: project pretax income (from operating margin analysis), then apply an estimated effective tax rate derived from historical rates and disclosures about expected changes.
AB InBev 2016 profitability drop was caused by the SABMiller acquisition (USD100B+ deal) — finance costs spiked from USD3.1B in 2015 to USD9.4B in 2016 (from 7.2% to 20.6% of revenue). Gross profit margin barely changed (60.7% → 60.9%). Common-size isolates the cause immediately.
