The fund invests at least 80% of assets in debt securities included in the Bloomberg U.S. Treasury Index. It maintains a dollar-weighted average maturity of one year or more. The adviser uses statistical sampling techniques based on duration, maturity, interest rate sensitivity, security structure, and credit quality to attempt to replicate the returns of the Bloomberg U.S. Treasury Index using a smaller number of securities.
