Short-Term Treasury Portfolio invests only in short-term U.S. Treasury securities, whose repayment is guaranteed by the full faith and credit of the U.S. government. This guarantee applies only to the securities in which the Portfolio invests, not to the Portfolio’s share price. Investments in debt securities typically decrease in value when interest rates rise. The Portfolio’s share price will fluctuate due to changes in interest rates, market conditions, and other factors.
