Profitability
Gross marginWeak
Among the 40% lowest rated companies in the industry
The gross result as a share of revenue — how much of the revenue is left after variable costs to cover the company's fixed costs.
Operating marginAverage
Around the average of companies in the same industry
EBIT as a share of revenue — the share of revenue remaining as earnings once all operating costs are covered. A key measure of earning power.
Net profit marginWeak
Among the 40% lowest rated companies in the industry
The profit for the year as a share of revenue — the company's ability to turn revenue into profit.
Return on equity (ROE)Strong
Among the 40% highest rated companies in the industry
Net profit as a percentage of equity — the return the owners earned on their invested capital this year.
Return on assets (ROA)Average

Net profit as a percentage of total assets — the return generated on the capital employed.
Return on net assets (RONA)Strong
Among the 40% highest rated companies in the industry
Profit relative to net assets (total assets minus total debt) — the ability to generate earnings from the net asset base alone.
Basic earning power (BEP)Average
Around the average of companies in the same industry
EBIT relative to total assets — the company's earning power before the effects of tax and financial leverage.
Capacity ratioAverage
Around the average of companies in the same industry
Shows how strongly fixed costs weigh on the gross result — a high ratio means fixed costs take only a small bite out of the earnings from basic operations.
Liquidity
Current ratioVery weak
Among the 20% lowest rated companies in the industry
Current assets relative to short-term debt — the ability to settle short-term obligations with current assets alone. Around 150% is considered satisfactory from a credit perspective.
Quick ratioWeak
Among the 30% lowest rated companies in the industry

Cash ratioVery weak
Among the 20% lowest rated companies in the industry
Cash relative to short-term debt — the ability to repay short-term obligations with cash alone.
Current assets to equityVery weak
Among the 10% lowest rated companies in the industry

Fixed assets to long-term capitalVery weak
Among the 10% lowest rated companies in the industry
Fixed assets relative to long-term capital (equity plus long-term liabilities). Below 100% means the long-term capital finances more than just the fixed assets — a healthier liquidity position.

Cash flow relative to profit — the ability to convert reported profits into accessible cash.

Total debt relative to the balance-sheet total — the share of the assets financed by debt rather than equity.
Debt to equityVery weak
Among the 10% lowest rated companies in the industry
Debt relative to equity — the company's leverage. A higher value means heavier reliance on debt financing.
Liabilities to equityVery weak
Among the 10% lowest rated companies in the industry
Total liabilities relative to equity — whether the company operates primarily on borrowed capital or on its own.
Income to debtAverage
Around the average of companies in the same industry

Among the 30% lowest rated companies in the industry
Financial expenses relative to total liabilities — the effective interest rate the company pays on its debt.
