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](https://learn.tradelabsai.com/fundamentals/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](https://learn.tradelabsai.com/fundamentals/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
```

**Example: High accruals as a warning**
Company A reports net income of $300 million and operating cash flow of $320 million. Company B reports net income of $300 million but operating cash flow of only $120 million, because receivables and inventory jumped. B's profits rely heavily on accruals. Research by Richard Sloan in 1996 found that companies with high accruals tended to underperform those with low accruals in following years, as their earnings proved less persistent.

## Common red flags

| Red flag | Possible issue |
|---|---|
| Receivables growing faster than revenue | Aggressive revenue recognition or collection problems. See [Working Capital](https://learn.tradelabsai.com/fundamentals/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](https://learn.tradelabsai.com/bonds-credit/default-probability/).
- **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

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