In determining the short-term liquidity of a firm, the current ratio is usually considered a better guide than the acid-test ratio, and the acid-test ratio is considered a better guide than the cash ratio. Why do you think this is? Do you agree or disagree with the ranking of current ratio first, acid-test ratio second, and cash ratio third for short-term liquidity determination? Discuss when the acid-test ratio would be preferred over the current ratio and when the cash ratio would be preferred over the acid-test ratio.
