Analyzing Income Statements

The income statement is where most valuation work begins, and also where management has the most room to shape the numbers. This module explains when revenue and expenses are recognized, how non-recurring items and accounting changes are presented, how to calculate basic and diluted earnings per share, and how common-size statements and margins reveal the drivers of profitability. You will be able to rebuild key figures yourself and judge how sustainable reported earnings are.

What you will learn

1. Apply the five-step revenue recognition model, including over-time recognition and principal-versus-agent judgments, and explain the analytical implications of revenue recognition choices.

Five steps: contract, performance obligations, transaction price, allocation, recognition when control transfers.
Over-time recognition uses a measure of progress such as cost-to-cost; estimate changes are caught up in the current period.
A principal reports revenue gross; an agent reports its net fee. Net income is the same either way.
Variable consideration is included only to the extent a significant reversal is unlikely.
Contract liabilities (cash before performance) and contract assets (performance before billing) link revenue to the balance sheet.

2. Describe how expenses are recognized, calculate depreciation under alternative methods, and evaluate how expense recognition choices and estimates affect reported results.

Matching: expenses directly tied to revenue are recognized with that revenue; period costs are expensed as incurred.
DDB applies 2/n to the opening carrying amount; residual value is a floor, not part of the formula.
Longer useful lives and higher residual values lower depreciation and raise profit without changing cash flow.
Bad debt expense is driven by the required allowance; write-offs reduce the allowance, not profit.
Changes in estimates are applied prospectively; compare policies with peers before comparing margins.

3. Describe the presentation of discontinued operations, unusual or infrequent items and accounting changes, and adjust reported earnings for non-recurring items.

Discontinued operations: reported net of tax, below income from continuing operations; excluded from forecasts.
Unusual or infrequent items: inside continuing operations, pre-tax; judge whether they really are one-off.
No extraordinary items under either IFRS or US GAAP.
Policy changes: retrospective. Estimate changes: prospective. Error corrections: restate prior periods.
Adjust non-recurring items on an after-tax basis when estimating sustainable earnings.

4. Calculate and interpret basic earnings per share, including the weighted average number of shares and the effect of share issues, repurchases, stock splits and stock dividends.

Basic EPS = (net income - preferred dividends) / weighted average common shares.
Deduct preferred dividends (cumulative preferred: whether or not declared); never deduct common dividends.
Time-weight share issues and repurchases by the months outstanding.
Stock splits and stock dividends are applied retroactively, including to shares issued earlier in the year.
EPS can rise through buybacks alone; check the drivers of growth.

5. Calculate and interpret diluted earnings per share using the if-converted and treasury stock methods, and identify antidilutive securities.

Convertible preferred: add back preferred dividends; add conversion shares.
Convertible bonds: add back interest x (1 - t); add conversion shares.
Options and warrants: add N x (P - X) / P shares using the average market price; no numerator change.
Exclude any antidilutive security; diluted EPS can never exceed basic EPS.
With a net loss, diluted loss per share equals basic loss per share.

6. Prepare and interpret common-size income statements and income-statement-based profitability ratios to compare companies and periods.

Common-size income statement: every line divided by revenue.
Gross, operating, pretax and net margins measure profitability at successive levels.
Similar margins can result from very different cost structures; look at each line.
Reclassify expenses and check revenue composition before comparing companies.
Interpret margins against history, peers and the business model.

Module at a glance

Revenue follows a five-step model based on transfer of control; principals report gross, agents report net.
Over-time revenue uses cumulative progress; estimate changes are caught up in the current period.
Depreciation methods and estimates change reported profit, not cash; estimate changes are prospective.
Discontinued operations sit net of tax below continuing operations; unusual items stay in continuing operations.
Basic EPS = (NI - preferred dividends) / weighted average shares, with splits applied retroactively.
Diluted EPS uses if-converted and treasury stock methods and excludes antidilutive securities.
Common-size statements and margins reveal where profit comes from; always check revenue composition.
