EBIT relative to total assets — the company's earning power before the effects of tax and financial leverage.

Liquidity
Current ratioStrong
Among the 30% highest 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.
