Vanguard Long Term Tax Exempt Fund (VWLUX)

The fund has no limitations on the maturity of individual securities but is expected to maintain a dollar-weighted average maturity of 10 to 25 years. At least 75% of the securities held by the fund are municipal bonds in the top three credit-rating categories as determined by a nationally recognized statistical rating organization (NRSRO) (e.g., Aaa, Aa, and A by Moody's Investors Service, Inc. (Moody's)) or, if unrated, determined to be of comparable quality by the advisor.
