In essence, the quick ratio, is a conservative version of the current ratio as it only includes the most liquid of the current assets: cash, marketable securities and receivables. The ratio takes into account the fact that certain current assets -- such as pre-paid expenses, taxes -- have already been paid in advance and cannot be converted back into cash. It also discounts inventory as it cannot be easily converted into cash, and that a company may not be able to realize the full carrying value of the inventory if it were to sell it quickly.
