Vanguard Intermediate-Term Treasury Fund Investor Shares 

This fund primarily allocates at least 80% of its assets to securities directly issued by the U.S. government, encompassing Treasury bills, notes, and bonds (including those protected against inflation). Additionally, it retains the option to invest in other debt instruments, such as those from federal agencies that are either backed, guaranteed, or owned by the federal government. A principal risk factor for this portfolio is its sensitivity to changes in interest rates; upward or downward shifts can result in lower bond valuations or a eventual decrease in the fund's income. This offering is ideal for investors seeking consistent interest income who are also prepared to accept moderate variations in both asset value and earnings.
