One common problem with the current ratio is that it is susceptible to "window dressing." If a firm has a current ratio of $1\mathrm{.}5$ prior to a year end, its managers can boost the current ratio for the year by:

Group of answer choices

Investing cash in marketable securities

Using cash to pay down accounts payable prior to year end

Speeding up collections of accounts receivable

Purchasing additional inventory on supplier credit
