The Vanguard Intermediate-Term Tax-Exempt Fund Admiral Shares aims to deliver a steady and moderate level of current income, which is exempt from federal personal income taxes. While the fund has no restrictions on the maturity of individual securities, its dollar-weighted average maturity is typically maintained between 6 and 12 years. The portfolio primarily consists of high-quality municipal bonds: at least 75% must be rated among the top three categories by a recognized credit agency, or deemed of comparable quality by the advisor if unrated.
