Quick Liquidity Ratio
  
See: Quick Ratio. See: Quick Assets. And yes, it's about liquidity. So um, see: Liquidity.
How quickly can you be liquid? In the numerator: Quick assets, i.e. assets that can be turned into cash within a year. In the denominator: Net liabilities and any net insurance liabilities or contingencies the company may have to pay another's bills.
A high ratio means that a company is very liquid, safe, stable, able to meet its monthly nut.
