Treasurers face multiple challenges when it comes toshort-term investments. Large corporates have oodles of cash, butthe returns they're earning at the short end are minimal. And moneymarket funds, typically one of the main repositories for companies'short-term cash, could become less attractive for corporates if theSecurities and Exchange Commission (SEC) goes through with some ofthe regulatory changes it has proposed.

A recent survey by PwC suggests that while corporate treasurers areexploring ways to achieve higher returns and prepare for possibleregulatory changes, for the most part they continue to take atraditional approach to short-term investing.

“Treasurers are clearly looking for ideas and opportunity forhow to get more bang for the buck out of their investmentportfolios,” said Peter Frank, a principal at PwC and leader of itsCorporate Treasury Solutions practice.
