Lesson 27 of 45

Not all earnings are equal. Two companies can report the same profit, but one earns it from steady, cash generating sales while the other relies on one off gains, aggressive accounting estimates or customers who have not paid. Earnings quality is the study of how reliable, repeatable and cash backed a company's reported profits are. High quality earnings support higher valuations; low quality earnings often come before disappointments, restatements or worse.

Signs of high quality earnings#

Sign	Why it matters
Operating cash flow close to or above net income	Profits turn into cash. See Cash Flow Statement
Stable margins and revenue growth	Fewer one off boosts
Conservative accounting choices	Revenue recognised cautiously, expenses not deferred
Small gap between GAAP and adjusted earnings	Fewer "special" exclusions. See Net Income and EPS
Clean audit opinions and simple structures	Less room for manipulation

Accruals#

Accruals are the non cash part of earnings: the difference between net income and operating cash flow.

accruals = net income - cash from operations
accrual ratio = accruals / average total assets

Common red flags#

Red flag	Possible issue
Receivables growing faster than revenue	Aggressive revenue recognition or collection problems. See Working Capital
Inventory build up	Weak demand; future write downs
Frequent "one off" charges	Recurring costs disguised as unusual
Rising capitalised costs	Expenses moved to the balance sheet
Changes in depreciation lives or reserves	Boosting profit through estimates
Large non operating gains	Profit from asset sales or investments
Frequent acquisitions	Organic growth hidden; complex accounting
Auditor changes or late filings	Possible disagreements
Executive pay tied to adjusted metrics	Incentive to flatter numbers

Screening models#

Beneish M score (1999): combines eight ratios, including receivables growth, gross margin trends and accruals, to estimate the probability that a company manipulates earnings.
Altman Z score: predicts bankruptcy risk from financial ratios. See Default Probability and Recovery Rate.
Piotroski F score: nine tests of profitability, leverage and efficiency, used to pick financially strong value stocks.

Famous accounting frauds#

Company	Year revealed	What happened
Enron	2001	Off balance sheet entities hid debt and inflated profits
WorldCom	2002	About $3.8 billion of operating expenses improperly capitalised, later found to be larger
Satyam	2009	Founder admitted inflating cash and profits
Luckin Coffee	2020	Fabricated sales of about $300 million
Wirecard	2020	€1.9 billion of cash said to exist did not

Many of these showed warning signs such as profits not matching cash flow. Short sellers and journalists raised concerns about several before they collapsed.

How traders use earnings quality#

Compare net income with operating cash flow over several years.
Read the reconciliation from GAAP to adjusted earnings.
Track receivables, inventory and capitalised costs relative to sales.
Read the notes and auditor's report.
Be sceptical of companies that consistently beat by a penny, which may be managing earnings to meet targets.
