Among the 10% lowest rated companies in the 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.

Among the 20% 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)Very weak

Net profit as a percentage of equity — the return the owners earned on their invested capital this year.
Return on assets (ROA)Very weak
Among the 20% lowest rated companies in the industry
Net profit as a percentage of total assets — the return generated on the capital employed.
Return on net assets (RONA)Very weak
Among the 10% lowest rated companies in the industry

Basic earning power (BEP)Very weak
Among the 10% lowest rated companies in the industry
EBIT relative to total assets — the company's earning power before the effects of tax and financial leverage.
Capacity ratioVery weak
Among the 10% lowest rated companies in the 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

Current assets to equityVery weak
Among the 10% lowest rated companies in the industry

Fixed assets to long-term capitalWeak
Among the 40% 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 debtVery weak
Among the 20% lowest rated companies in the industry

Financial expenses relative to total liabilities — the effective interest rate the company pays on its debt.
