We learned from Financial Week about a recent study by Greenwich Associates entitled, "In U.S. Corporate Cash Portfolios, A Flight To Quality." The release from Greenwich says, "U.S. companies are reducing risk levels in their cash investment portfolios and cutting return targets on short-term investments." Expected returns on cash investments for the almost 300 large companies surveyed have been reduced from 4.9% to 3.7%, which "reflects a general flight to quality in the short-term investment portfolios".
