meaning of cash
companies using modern cash management techniques invest any temporary excess amounts of cash in highly liquid ( i.e., can be readily sold at current market prices), short-term investment (e.g., money maney market funds nad Treasury bills) for periods as short as one or two days. As a result, for purposes of the cash flow statement, cash means the sum of actual cash and these short-term investments; the sum is formally called cash and cash equivalents. The Financial Accounting Standards Board (FASB) defines cash equivslents as highly liquib investments that are readily convertible to known amounts of cash and that mature in no more than 90 days from the date of the financial statement
