## 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) | 35.3% | S100YK2Q |
| Fixed assets ÷ total assets | 15.2% | S100YK2Q |
| Goodwill ÷ parent equity | 3.9% | S100YK2Q |

Goodwill over 4 years: 312 → 5,399 JPY; total investing cash flow: -35,704 JPY. This does not imply causation.

### 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) | 28.5% |
| Cash ÷ revenue | 66.0% |
| Net cash (cash − interest-bearing debt) | — |
| Net debt ÷ operating cash flow | — |
| Cash conversion (operating CF ÷ operating income) | — |
| Cash vs. profit gap | -13,223 JPY mn (of net income -616.7%) |
| Shareholder returns / net income | 412.4% |
| Shareholder returns / FCF | — |
| Shareholder payments — dividends / net income | 303.1% |
| Shareholder payments — dividends / FCF | — |
| CapEx intensity (capex ÷ revenue) | 7.1% |
| Investing CF relative to operating CF | — |

## 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.
