## 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) | 22.3% | S100YK61 |
| Fixed assets ÷ total assets | 17.5% | S100YK61 |
| Goodwill ÷ parent equity | 2.2% | S100YK61 |

### 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 | 19.6% |
| Net cash (cash − interest-bearing debt) | — |
| Net debt ÷ operating cash flow | — |
| Cash conversion (operating CF ÷ operating income) | 199.2% |
| Cash vs. profit gap | 711 JPY mn (of net income 74.3%) |
| Shareholder returns / net income | 22.2% |
| Shareholder returns / FCF | 20.5% |
| Shareholder payments — dividends / net income | 18.1% |
| Shareholder payments — dividends / FCF | 16.8% |
| CapEx intensity (capex ÷ revenue) | 2.1% |
| Investing CF relative to operating CF | 39.7% |

## 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.
