## 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 |

| Fixed assets ÷ total assets | 38.4% | S100YKNS |
| Goodwill ÷ parent equity | — | —, S100YKNS |

### 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) | 11.8% |

| CapEx intensity (capex ÷ revenue) | 8.9% |
| Investing CF relative to operating CF | 64.8% |

## 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.
