## Asset intensity and goodwill

Ratios are derived from reported values. Goodwill is used only when separately reported, never inferred from combined intangible assets.

| Metric | Value | Sources |
| --- | ---: | ---: |
| Asset intensity (fixed assets ÷ revenue) | 44.6% | S100WQ16 |
| Fixed assets ÷ total assets | 50.2% | S100WQ16 |
| Goodwill ÷ parent equity | 5.6% | S100WQ16 |

### Cash quality

Net cash = cash − interest-bearing debt. Net debt ratio = (interest-bearing debt − cash) ÷ positive operating cash flow. Omit when debt components are incomplete; other ratios are derived from reported figures.

| Metric | Value |
| --- | ---: |
| Cash ratio (cash ÷ total assets) | 15.3% |
| Cash ÷ revenue | 13.6% |
| Net cash (cash − interest-bearing debt) | -¥274.8M |
| Net debt ÷ operating cash flow | 1.45× |

| CapEx intensity (capex ÷ revenue) | 3.0% |
| Investing CF relative to operating CF | 99.9% |

## ROA and ROE

ROE is decomposed into net margin × asset turnover × financial leverage. Leverage can raise ROE, so the ratio alone does not assess a company's condition. Ending balances are used without a prior year; total equity approximates parent equity when unavailable.
