Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


1 Year	3 Years	5 Years	10 Years
$17	$55	$96	$217

Primary Investment Policies
The Fund invests at least 80% of its assets in a variety of high-quality, short-term Pennsylvania municipal securities whose income is exempt from federal and Pennsylvania taxes. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized statistical rating organizations (NRSROs) (or by one, if only one NRSRO has rated the security). If unrated, the security must be determined by Vanguard to be of quality equivalent to those in the two highest credit-quality categories for short-term securities. The Fund invests in securities with effective maturities of 397 days or less, maintains a dollar-weighted average maturity of 60 days or less, and maintains a dollar-weighted average life of 120 days or less.

Primary Risks
The Fund is designed for investors with a low tolerance for risk; however, the Fund’s performance could be hurt by:

• State-specific risk, which is the chance that developments in Pennsylvania will adversely affect the securities held by the Fund. Because the Fund invests primarily in securities issued by Pennsylvania and its municipalities, it is more vulnerable to unfavorable developments in Pennsylvania than are funds that invest in municipal securities of many states. Unfavorable developments in any economic sector may have far-reaching ramifications on the overall Pennsylvania municipal market.

• Income risk, which is the chance that the Fund’s income will decline because of falling interest rates. Because the Fund’s income is based on short-term interest rates—which can fluctuate significantly over short periods—income risk is expected to be high.

• Credit risk, which is the chance that the issuer of a security will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuer’s ability to make such payments will cause the price of that security to decline. Credit risk should be very low for the Fund because it invests primarily in securities that are considered to be of high quality.

• Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

• Nondiversification risk, which is the chance that the Fund’s performance may be hurt disproportionately by the poor performance of relatively few securities. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with other mutual funds.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1 per share, it is possible to lose money by investing in the Fund.
