On May 23, 2013, the Board approved changing the Fund’s fiscal year from Feb. 28/29 to Aug. 31. This change will be effective for the period ended Aug. 31, 2013. Therefore, the managers’ commentary below applies to the partial year between March 1, 2013 and Aug. 31, 2013. In future editions of the Fund’s annual report, the managers’ commentary will once again report on the Fund’s entire fiscal year.

A cautious approach amid economic turbulence

As the reporting period got under way in March, we were closely watching developments across a range of fronts, including: the fiscal negotiations that were supposed to be happening in Washington, D.C.; U.S. economic growth; developments in Europe and other economies around the world; and bond-specific developments in Puerto Rico issues, which were coming under tremendous pressure.

In light of such macroeconomic turbulence, we generally took a cautious approach throughout the reporting period, allowing our security selection process and our focus on income to guide our investment decisions.

As we moved into the summer months of 2013, it appeared that investors were increasingly concerned about when (and by how much) the U.S. Federal Reserve would begin to wind down its $85 billion-per-month bond-buying program (the so-called “quantitative easing” program). Although the winding down did not yet commence, the market’s fears were realized when three Fed communications — two in May and one in June — led to a market selloff that resulted in significant negative returns for fixed income instruments.

Concerns about rising rates pull markets lower

The string of Fed communications mentioned above led many investors to worry about the possibility of rising interest rates, causing what could be described as widespread panic in the market. Municipal bond mutual funds began suffering heavy outflows. In order to meet redemption orders, many mutual

fund managers were forced to sell bonds into an environment of weak demand, driving prices down even further. Certainly, the municipal market was not alone in being affected by this negative feedback loop; but we believe the relatively smaller audience for municipal bonds caused prices to fall harder and faster than other types of securities.

In addition to the distress mentioned above, municipal markets were weakened further by the city of Detroit’s bankruptcy filing in July. Investors appeared to believe that the problems facing Detroit’s finances could be germane to the municipal bond market as a whole. As such, investors and prognosticators painted a broadly negative picture, despite the fact that, in our assessment, credit quality generally remained strong throughout municipal markets.

Pennsylvania’s economic environment

The unemployment rate in Pennsylvania was 7.5% in July, unchanged for the third consecutive month (data: Pennsylvania Department of Labor and Industry). While this is relatively encouraging, especially in light of the headwinds that the economy has faced since the national recession, there is a way to go before the state is back to full economic health. All the same, the state continues to support a diverse economy, with notable activity in sectors that include healthcare, education, financial services, transportation, trade, and manufacturing.

Pennsylvania Governor Tom Corbett signed the state’s budget for fiscal 2014 on June 30, 2013. The $28.4 billion budget calls for an increase in total government spending, with an emphasis on areas such as education, care for older Pennsylvanians, and public safety.

Within the Fund

For the six-month period between March 1, 2013 and Aug. 31, 2013, Delaware Tax-Free Pennsylvania Fund (Class A shares at net asset value, with all distributions reinvested) returned -7.94%. The Fund’s benchmark, the Barclays Municipal Bond Index, returned -5.60% during the same period. For complete, annualized performance of Delaware Tax-Free Pennsylvania Fund, please see the table on page 4.

Factors behind the Fund’s underperformance included its relative overweight allocation to securities of marginally lower quality (in particular those rated on the lower end of the investment grade spectrum), which tended to lag the performance of bonds at the higher end of the ratings spectrum.

At the sector level, the Fund’s performance versus the benchmark was hampered by a relative overweight to the healthcare sector; collectively, healthcare bonds within the index trailed the return posted by the broader index. Relative underweights to general obligation bonds (often referred to as “GOs”) likewise had negative effects on the Fund’s performance versus the benchmark, as GOs within the index collectively outperformed the broader index.

The negative effects described above were offset somewhat by positive effects from sources such as the Fund’s underweight allocation to transportation bonds; index constituents within the transportation sector trailed the broader index, and the Fund’s relatively milder emphasis on the sector was therefore beneficial.

On an individual bond basis, Puerto Rico bonds ended the period among the weakest holdings within the Fund. They were handcuffed by the environment of risk aversion mentioned above, and at least two of the Fund’s Puerto Rico bonds suffered a decline of more than 20%. The two bonds were issued by the Puerto Rico Sales Tax Financing Corporation. The first, issued as a general purpose bond, is backed by a dedicated sales tax; its coupon rate is 5.5% and it matures on Aug. 1, 2042. The second bond, likewise issued to raise funds for general purposes and backed by a dedicated sales tax, is a zero-coupon bond with a maturity date of Aug. 1, 2032.

Still at the individual bond level, the effects of the declines above were offset mildly by bonds that included an issue by the Pennsylvania Economic Development Financial Authority to support the Dr. Gertrude A. Barber Center (a facility that provides educational services to people with developmental disabilities). The issue has a coupon rate of 5.9% and matures on Dec. 1, 2030. Another positive contributor was issued by the Lehigh-Northampton Airport Authority, with a coupon of 6.0% and a maturity date of May 15, 2025. The bond’s proceeds are being used to fund general operations at the Lehigh Valley International Airport.

The performance data quoted represent past performance; past performance does not guarantee future results. Investment return and principal value will fluctuate so your shares, when redeemed, may be worth more or less than their original cost. Please obtain the performance data current for the most recent month end by calling 800 523-1918 or visiting our website at delawareinvestments.com/performance. Current performance may be lower or higher than the performance data quoted.

¹ Returns reflect the reinvestment of all distributions and are presented both with and without the applicable sales charges described below. Returns do not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares.

Expense limitations were in effect for certain classes during some or all of the periods shown in the “Fund performance” chart. Expenses for each class are listed on the “Fund expense ratios” table on page 5. Performance would have been lower had expense limitations not been in effect.

Class A shares are sold with a maximum front-end sales charge of 4.50%, and have an annual distribution and service fee of 0.30% of average daily net assets. This fee has been contractually limited to 0.25% of average daily net assets through Dec. 29, 2014. Furthermore, the Board has adopted a formula for calculating 12b-1 plan fees for the Fund’s Class A shares that went into effect on June 1, 1992. The Fund’s Class A shares are currently subject to a blended 12b-1 fee equal to the sum of: (i) 0.10% of average daily net assets representing shares acquired prior to June 1, 1992, and (ii) 0.30% (currently limited to 0.25%) of average daily net assets representing shares acquired on or after June 1, 1992. All Class A shares currently bear 12b-1 fees at the same rate, the blended rate, currently 0.24% of average daily net assets, based on the formula described above. This method of calculating Class A 12b-1 fees may be discontinued at the sole discretion of the Board. Performance for Class A shares, excluding sales charges, assumes that no front-end sales charge applied.

Class B shares may be purchased only through dividend reinvestment and certain permitted exchanges as described in the prospectus. Please see the prospectus for additional information on Class B shares. Class B shares

have a contingent deferred sales charge that declines from 4.00% to zero depending on the period of time the shares are held. They are also subject to an annual distribution and service fee of 1.00% of average daily net assets. This fee has been contractually limited to 0.25% of average daily net assets from July 1, 2013 through Dec. 29, 2014. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. Ten-year performance figures for Class B shares reflect conversion to Class A shares after approximately eight years.

Class C shares are sold with a contingent deferred sales charge of 1.00% if redeemed during the first 12 months. They are also subject to an annual distribution and service fee of 1.00% of average daily net assets.

Performance for Class B and C shares, excluding sales charges, assumes either that contingent deferred sales charges did not apply or that the investment was not redeemed.

The “Fund performance” table and the “Performance of a $10,000 investment” graph do not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares.

Fixed income securities and bond funds can lose value, and investors can lose principal, as interest rates rise. They also may be affected by economic conditions that hinder an issuer’s ability to make interest and principal payments on its debt.

The Fund may also be subject to prepayment risk, the risk that the principal of a fixed income security that is held by the Fund may be prepaid prior to maturity, potentially forcing the Fund to reinvest that money at a lower interest rate.

Substantially all dividend income derived from tax-free funds is exempt from federal income tax. Some income may be subject to the federal alternative minimum tax (AMT) that applies to certain investors. Capital gains, if any, are taxable.

Funds that invest primarily in one state may be more susceptible to the economic, regulatory, and other factors of that state than funds that invest more broadly.

Bond ratings are determined by a nationally recognized statistical rating organization.

² The Fund’s expense ratios, as described in the most recent prospectus, are disclosed in the following “Fund expense ratios” table. Delaware Management Company has agreed to reimburse certain expenses and/or waive certain fees (excluding certain fees and expenses) in order to prevent total annual fund operating expenses from exceeding 0.64% of the Fund’s average daily net assets from June 28, 2013, through Dec. 29, 2014. Please see the most recent prospectus and any applicable supplement(s) for additional information on these fee waivers and/or reimbursements.

Performance of a $10,000 investment ¹
Average annual total returns from Aug. 31, 2003, through Aug. 31, 2013

¹ The “Performance of a $10,000 investment” graph assumes $10,000 invested in Class A shares of the Fund on Aug. 31, 2003, and includes the effect of a 4.50% front-end sales charge and the reinvestment of all distributions. The graph does not reflect the deduction of taxes the shareholders would pay on Fund distributions or redemptions of Fund shares. Expense limitations were in effect for some or all of the periods shown. Performance would have been lower had expense limitations not been in effect. Expenses are listed in the “Fund expense ratios” table on page 5. Please note additional details on pages 4 through 6.

The chart also assumes $10,000 invested in the Barclays Municipal Bond Index as of Aug. 31, 2003. The Barclays Municipal Bond Index measures the total return performance of the long-term, investment grade tax-exempt bond market.

Index performance returns do not reflect any management fees, transaction costs, or expenses. Indices are unmanaged and one cannot invest directly in an index. Past performance is not a guarantee of future results.

Performance of other Fund classes will vary due to different charges and expenses.

Disclosure of Fund expenses
For the six-month period from March 1, 2013 to August 31, 2013 (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from March 1, 2013 to Aug. 31, 2013.

Actual expenses

The first section of the table shown, “Actual Fund return,” provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The second section of the table shown, “Hypothetical 5% return,” provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund’s expenses shown in the table reflect fee waivers in effect. The expenses shown in the table assume reinvestment of all dividends and distributions.
