Mutual fund advisory services provided by Delaware Management Company, a series of Delaware Management Business Trust, which is a registered investment advisor. (C) 2005 Delaware Distributors, L.P. DISCLOSURE For the Period March 1, 2005 to August 31, 2005 of fund expenses As a shareholder of the Fund, you may 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 period March 1, 2005 to August 31, 2005. 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 expenses shown in the table assume reinvestment of all dividends and distributions.

See accompanying notes 11 NOTES DELAWARE TAX-FREE PENNSYLVANIA FUND TO FINANCIAL STATEMENTS August 31, 2005 (Unaudited) Delaware Group State Tax-Free Income Trust (the "Trust") is organized as a Delaware statutory trust and offers one series: Delaware Tax-Free Pennsylvania Fund (the "Fund"). The Trust is an open-end investment company. The Fund is considered non-diversified under the Investment Company Act of 1940, as amended, and offers Class A, Class B and Class C shares. Class A shares are sold with a front-end sales charge of up to 4.50%. Class B shares are sold with a contingent deferred sales charge that declines from 4% to zero depending upon the period of time the shares are held. Class B shares will automatically convert to Class A shares on a quarterly basis approximately eight years after purchase. Class C shares are sold with a contingent deferred sales charge of 1%, if redeemed during the first 12 months. The investment objective of the Delaware Tax-Free Pennsylvania Fund is to seek a high level of current interest income exempt from federal income tax and certain Pennsylvania state and local taxes, consistent with the preservation of capital. 1. SIGNIFICANT ACCOUNTING POLICIES The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by the Fund. Security Valuation -- Long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. Other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Fund's Board of Trustees. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges among dealers, or news events). Federal Income Taxes -- The Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. Class Accounting -- Investment income and common expenses are allocated to the classes of the Fund on the basis of "settled shares" of each class in relation to the net assets of the Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Use of Estimates -- The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Other -- Expenses common to all funds within the Delaware Investments(R) Family of Funds are allocated amongst the funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date). Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Interest income is recorded on the accrual basis. Discounts and premiums are amortized to interest income over the lives of the respective securities. The Fund declares dividends daily from net investment income and pays such dividends monthly and declares and pays distributions from net realized gain on investments, if any, annually. The Fund receives earnings credits from its custodian when positive cash balances are maintained, which are used to offset custody fees. The earnings credits for the six months ended August 31, 2005 were approximately $15,601. The expense paid under the above arrangement is included in custodian fees on the Statement of Operations with the corresponding expense offset shown as "expense paid indirectly." 2. Investment Management, Administration Agreements and Other Transactions with Affiliates In accordance with the terms of its investment management agreement, the Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the investment manager, an annual fee which is calculated daily at the rate of 0.55% on the first $500 million of average daily net assets of the Fund, 0.50% on the next $500 million, 0.45% on the next $1.5 billion, and 0.425% on average daily net assets in excess of $2.5 billion. Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides accounting, administration, dividend disbursing and transfer agent services. Effective May 19, 2005, the Fund pays DSC a monthly fee computed at the annual rate of 0.04% of the Fund's average daily net assets for accounting and administration services. Prior to May 19, 2005, the Fund paid DSC a monthly fee based on average net assets subject to certain minimums for accounting and administration services. The Fund pays DSC a monthly fee based on the number of shareholder accounts for dividend disbursing and transfer agent services. Pursuant to a distribution agreement and distribution plan, the Fund pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual distribution and service fee not to exceed 0.30% of the average daily net assets of the Class A shares and 1.00% of the average daily net assets of the Class B and C shares. The Board of Trustees 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 total 12b-1 fees to be paid by Class A shareholders of the Fund will be sum of 0.10% of the average daily net assets representing shares that were acquired prior to June 1, 1992 and 0.30% of the average daily net assets representing shares that were acquired on or after June 1, 1992. All Class A shareholders will bear 12b-1 fees at the same rate, the blended rate based upon the allocation of the 0.10% and 0.30% rates described above. DDLP has contracted to waive distribution and service fees through June 30, 2006 in order to prevent distribution and service fees of Class A shares from exceeding 0.25% of average daily net assets. This contractual waiver is applied to the shares of the Fund that were acquired on or after June 1, 1992 in calculating the applicable 12b-1 fee rate. At August 31, 2005, the Fund had liabilities payable to affiliates as follows: Investment management fees payable to DMC $282,822 Dividend disbursing, transfer agent, accounting and administration fees and other expenses payable to DSC 54,716 Other expenses payable to DMC and affiliates* 187,216 *DMC, as part of its administrative services, pays operating expenses on behalf of the Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, registration fees and trustees' fees. As provided in the investment management agreement, the Fund bears the cost of certain legal services expenses, including internal legal services provided to the Fund by DMC employees. For the six months ended August 31, 2005, the Delaware Tax-Free Pennsylvania Fund was charged $16,074 for internal legal services provided by DMC. 12 NOTES DELAWARE TAX-FREE PENNSYLVANIA FUND TO FINANCIAL STATEMENTS (CONTINUED) 2. INVESTMENT MANAGEMENT, ADMINISTRATION AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES (CONTINUED) For the six months ended August 31, 2005, DDLP earned $21,862 for commissions on sales of the Fund's Class A shares. For the six months ended August 31, 2005, DDLP received gross contingent deferred sales charge commissions of $3,550, $5,247 and $622 on redemption of the Fund's Class A, Class B and Class C shares, respectively. These commissions were entirely used to offset up-front commissions previously paid by DDLP to broker-dealers on sales of those shares. Certain officers of DMC, DSC and DDLP are officers and/or trustees of the Trust. These officers and trustees are paid no compensation by the Fund. 3. INVESTMENTS For the six months ended August 31, 2005, the Fund made purchases of $48,240,692 and sales of $66,356,858 of investment securities other than short-term investments. At August 31, 2005, the cost of investments for federal income tax purposes has been estimated since the final tax characteristics cannot be determined until fiscal year end. At August 31, 2005, the cost of investments was $562,877,857. At August 31, 2005, the net unrealized appreciation was $47,835,509 of which $47,837,550 related to unrealized appreciation of investments and $2,041 related to unrealized depreciation of investments. 4. DIVIDEND AND DISTRIBUTION INFORMATION Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. Additionally, net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the six months ended August 31, 2005 and the year ended February 28, 2005 was as follows: Six Months Year Ended Ended 8/31/05* 2/28/05 ----------- ----------- Tax-exempt income $13,388,812 $28,586,626 *Tax information for the six months ended August 31, 2005 is an estimate and the tax character of dividends and distributions may be redesignated at fiscal year end. The components of net assets are estimated since the final tax characteristics cannot be determined until fiscal year end. As of August 31, 2005, the estimated components of net assets on a tax basis were as follows: Shares of beneficial interest $591,826,744 Capital loss carryforwards (19,708,151) Unrealized appreciation of investments 47,835,509 ------------ Net assets $619,954,102 ============ The difference between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales. For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. Capital loss carryforwards remaining at February 28, 2005 will expire as follows: $9,193,068 expires in 2008, $8,323,306 expires in 2009 and $1,161,652 expires in 2010. For the six months ended August 31, 2005, the Fund had capital losses of $1,030,125, which may be added to the capital loss carryforwards. 5. CAPITAL SHARES Transactions in capital shares were as follows: Six Months Year Ended Ended 8/31/05 2/28/05 Shares sold: Class A 1,009,930 2,429,500 Class B 59,583 104,213 Class C 127,934 146,265 Shares issued upon reinvestment of dividends and distributions: Class A 906,683 1,952,449 Class B 24,102 60,707 Class C 11,006 22,433 ---------- ---------- 2,139,238 4,715,567 ---------- ---------- Shares repurchased: Class A (3,500,289) (8,183,287) Class B (483,261) (898,361) Class C (34,210) (62,560) ---------- ---------- (4,017,760) (9,144,208) ---------- ---------- Net decrease (1,878,522) (4,428,641) ========== ========== For the six months ended August 31, 2005 and the year ended February 28, 2005, 339,915 Class B shares were converted to 339,696 Class A shares valued at $2,767,656 and 510,991 Class B shares were converted to 510,991 Class A shares valued at $4,123,073, respectively. The respective amounts are included in Class B redemptions and Class A subscriptions in the table above and the Statements of Changes in Net Assets. 6. LINE OF CREDIT The Fund, along with certain other funds in the Delaware Investments(R) Family of Funds (the "Participants"), participates in a $183,100,000 revolving line of credit facility to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Participants are charged an annual commitment fee, which is allocated across the Participants on the basis of each fund's allocation of the entire facility. The Participants may borrow up to a maximum of one third of their net assets under the agreement. The Fund had no amounts outstanding as of August 31, 2005, or at any time during the period. 13 NOTES DELAWARE TAX-FREE PENNSYLVANIA FUND TO FINANCIAL STATEMENTS (CONTINUED) 7. CREDIT AND MARKET RISK The Fund concentrates its investments in securities issued by Pennsylvania municipalities. The value of these investments may be adversely affected by new legislation within Pennsylvania, regional or local economic conditions, and differing levels of supply and demand for municipal bonds. Many municipalities insure repayment for their obligations. Although bond insurance reduces the risk of loss due to default by an issuer, such bonds remain subject to the risk that market value may fluctuate for other reasons and there is no assurance that the insurance company will meet its obligations. These securities have been identified in the Statement of Net Assets. The Fund may invest in inverse floating rate securities ("inverse floaters"), a type of derivative tax-exempt obligation with floating or variable interest rates that move in the opposite direction of short-term interest rates, usually at an accelerated speed. Consequently, the market values of inverse floaters will generally be more volatile than other tax-exempt investments. Such securities are denoted on the Statement of Net Assets. The Fund may invest in advanced refunded bonds, escrow secured bonds or defeased bonds. Under current federal tax laws and regulations, state and local government borrowers are permitted to refinance outstanding bonds by issuing new bonds. The issuer refinances the outstanding debt to either reduce interest costs or to remove or alter restrictive covenants imposed by the bonds being refinanced. A refunding transaction where the municipal securities are being refunded within 90 days or less from the issuance of the refunding issue is known as a "current refunding". "Advance refunded bonds" are bonds in which the refunded bond issue remains outstanding for more than 90 days following the issuance of the refunding issue. In an advance refunding, the issuer will use the proceeds of a new bond issue to purchase high grade interest bearing debt securities which are then deposited in an irrevocable escrow account held by an escrow agent to secure all future payments of principal and interest and bond premium of the advance refunded bond. Bonds are "escrowed to maturity" when the proceeds of the refunding issue are deposited in an escrow account for investment sufficient to pay all of the principal and interest on the original interest payment and maturity dates. Bonds are considered "pre-refunded" when the refunding issue's proceeds are escrowed only until a permitted call date or dates on the refunded issue with the refunded issue being redeemed at that time, including any required premium. Bonds become "defeased" when the rights and interests of the bondholders and of their lien on the pledged revenues or other security under the terms of the bond contract are substituted with an alternative source of revenues (the escrow securities) sufficient to meet payments of principal and interest to maturity or to the first call dates. Escrowed secured bonds will often receive a rating of AAA from Moody's, S&P, and/or Fitch due to the strong credit quality of the escrow securities and the irrevocable nature of the escrow deposit agreement. The Fund may invest up to 10% of its total assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. At August 31, 2005, there were no Rule 144A securities and no securities have been determined to be illiquid under the Fund's Liquidity Procedures. While maintaining oversight, the Board of Trustees has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund's limitation on investments in illiquid assets. 8. CONTRACTUAL OBLIGATIONS The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote. 14 OTHER DELAWARE TAX-FREE PENNSYLVANIA FUND FUND INFORMATION August 31, 2005 (Unaudited) BOARD CONSIDERATION OF DELAWARE TAX-FREE PENNSYLVANIA FUND INVESTMENT ADVISORY AGREEMENT At a meeting held on May 18-19, 2005 (the "Annual Meeting"), the Board of Trustees, including a majority of disinterested or independent Trustees, approved the renewal of the Investment Advisory Agreement for the Delaware Tax-Free Pennsylvania Fund (the "Fund"). In making its decision, the Board considered information furnished throughout the year at regular Board meetings, as well as information prepared specifically in connection with the Annual Meeting. Information furnished and discussed throughout the year included reports detailing Fund performance, investment strategies, expenses, compliance matters and other services provided by Delaware Management Company ("DMC"), the investment advisor. Information furnished specifically in connection with the Annual Meeting included materials provided by DMC and its affiliates ("Delaware Investments") concerning, among other things, the level of services provided to the Fund, the costs of such services to the Fund, economies of scale and the financial condition and profitability of Delaware Investments. In addition, in connection with the Annual Meeting, the Board separately received and reviewed independent historical and comparative reports prepared by Lipper Inc. ("Lipper"), an independent statistical compilation organization. The Lipper reports compared the Fund's investment performance and expenses with those of other comparable mutual funds. The Board also requested and received certain supplemental information regarding management's policy with respect to advisory fee levels and its philosophy with respect to breakpoints; the structure of portfolio manager compensation; the investment manager's profitability organized by client type, including the Fund; and any constraints or limitations on the availability of securities in certain investment styles which might inhibit the advisor's ability to fully invest in accordance with the Fund's policies. In considering such materials, the independent Trustees received assistance and advice from and met separately with independent counsel and representatives from Lipper. At the meeting with representatives from Lipper, Jude Driscoll, Chairman of the Delaware Investments Family of Funds, and Chairman and Chief Executive Officer of the investment advisor, was present to respond to questions raised by Lipper and the independent Trustees. While the Board considered the Investment Advisory Agreements for all of the funds in the Delaware Investments Family of Funds at the same Board meeting, information was provided and considered by the Board for each fund individually. In approving the continuance of the Investment Advisory Agreement for the Fund, the Board, including a majority of independent Trustees, determined that the existing advisory fee structure was fair and reasonable and that the continuance of the Investment Advisory Agreement was in the best interests of the Fund and its shareholders. While attention was given to all information furnished, the following discusses the primary factors relevant to the Board's deliberations and determination, including those relating to the selection of the investment advisor and the approval of the advisory fee. NATURE, EXTENT AND QUALITY OF SERVICE. Consideration was given to the services provided by Delaware Investments to the Fund and its shareholders. In reviewing the nature, extent and quality of services, the Board emphasized reports furnished to it throughout the year at regular Board meetings covering matters such as the compliance of portfolio managers with the investment policies, strategies and restrictions for the Fund, the compliance of management personnel with the Code of Ethics adopted throughout the Delaware Investments Family of Funds complex, the adherence to fair value pricing procedures as established by the Board, and the accuracy of net asset value calculations. The Board noted that it was pleased with the current staffing of the Fund's investment advisor during the past year, the emphasis on research and the compensation system for advisory personnel. Favorable consideration was given to DMC's efforts to maintain, and in some instances increase, financial and human resources committed to fund matters. Other factors taken into account by the Board were Delaware Investments' preparedness for, and response to, legal and regulatory matters. The Board also considered the transfer agent and shareholder services provided to Fund shareholders by Delaware Investments' affiliate, Delaware Service Company, Inc., noting the receipt by such affiliate of the DALBAR Pyramid Award in four of the last six years and the continuing expenditures by Delaware Investments to increase and improve the scope of shareholder services. Additionally, the Board noted the extent of benefits provided to Fund shareholders for being part of the Delaware Investments Family of Funds, including the privilege to exchange investments between the same class of funds without a sales charge, the ability to reinvest Fund dividends into other funds and the privilege to combine holdings in other funds to obtain a reduced sales charge. The Board was satisfied with the nature, extent and quality of the overall services provided by Delaware Investments. INVESTMENT PERFORMANCE. The Board considered the investment performance of DMC and the Fund. The Board was pleased by DMC's investment performance, noting Barron's ranking of the Delaware Investments Family of Funds in the top quartile of mutual fund families for 2002 - 2004. The Board placed significant emphasis on the investment performance of the Fund in view of its importance to shareholders. While consideration was given to performance reports and discussions with portfolio managers at Board meetings throughout the year, particular attention in assessing performance was given to the Lipper reports furnished for the Annual Meeting. The Lipper reports prepared for the Fund showed the investment performance of its Class A shares in comparison to a group of similar funds as selected by Lipper (the "Performance Universe"). A fund with the highest performance is ranked first, and a fund with the lowest is ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25% - the second quartile; the next 25% - the third quartile; and the lowest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for the Fund was shown for the past one, three, five and 10 year periods ended February 28, 2005. The Board noted its objective that the Fund's performance be at or above the median of its Performance Universe. The following paragraph summarizes the performance results for the Fund and the Board's view of such performance. The Performance Universe for this Fund consisted of the Fund and all retail and institutional Pennsylvania municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund's total return for the one and three year periods was in the first quartile of such Performance Universe. The report further showed that the Fund's total return for the five year period was in the second quartile and the Fund's total return for the 10 year period was in the third quartile. The Board was satisfied with such performance. 15 OTHER DELAWARE TAX-FREE PENNSYLVANIA FUND FUND INFORMATION (CONTINUED) BOARD CONSIDERATION OF DELAWARE TAX-FREE PENNSYLVANIA FUND INVESTMENT ADVISORY AGREEMENT (CONTINUED) COMPARATIVE EXPENSES. The Board considered expense comparison data for the Delaware Investments Family of Funds, Delaware Investments' institutional separate account business and other lines of business at Delaware Investments. The Board stated its belief that, given the differing level of service provided to Delaware Investments' various clients and other factors that related to the establishment of fee levels, variations in the levels of fees and expenses were justified. The Board placed significant emphasis on the comparative analysis of the management fees and total expense ratios of the Fund compared with those of a group of similar funds as selected by Lipper (the "Expense Group") and among the other Delaware Investments funds. In reviewing comparative costs, the Fund's contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees (as reported by each fund) of other funds within the Expense Group, taking into effect any applicable breakpoints and fee waivers. The Fund's total expenses were also compared with those of its Expense Group. The Lipper total expenses, for comparative consistency, were shown by Lipper for Class A shares and compared total expenses including 12b-1 and non-12b-1 service fees. The Board noted its objective to limit the Fund's total expense ratio to an acceptable range as compared to the median of the Expense Group. The following paragraph summarizes the expense results for the Fund and the Board's view of such expenses. The expense comparisons for the Fund showed that its management fee and total expenses were in the quartile with the second highest expenses of its Expense Group. The Board noted that the Fund's total expenses were not in line with the Board's objective. In evaluating the total expenses, the Board considered waivers in place through June 2006. The Board was satisfied with management's efforts to improve the Fund's total expense ratio and bring it in line with the Board's objective. MANAGEMENT PROFITABILITY. The Board considered the level of profits, if any, realized by Delaware Investments in connection with the operation of the Fund. In this respect, the Board reviewed the Investment Management Profitability Analysis that addressed the overall profitability of Delaware Investments' business in providing management and other services to each of the individual funds and the Delaware Investments Family of Funds as a whole. Specific attention was given to the methodology followed in allocating costs for the purpose of determining profitability. Management stated that the level of profits of Delaware Investments, to a certain extent, reflected operational cost savings and efficiencies initiated by Delaware Investments. The Board considered Delaware Investments' expenditures to improve services provided to fund shareholders and to meet additional regulatory and compliance requirements resulting from the Sarbanes-Oxley Act and recent SEC initiatives. The Board also considered the extent to which Delaware Investments might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as service provider to the Delaware Investments Family of Funds, the benefits from allocation of fund brokerage to improve trading efficiencies and the use of "soft" commission dollars to pay for proprietary and non-proprietary research. At the Board's request, management also provided information relating to Delaware Investments' profitability by client type. The information provided set forth the revenue, expenses and pre-tax income/loss attributable to the Delaware Investments Family of Funds, Delaware Investments' separate account business and other lines of business at Delaware Investments. Emphasis was given to the level and type of service provided to the various clients. The Board was satisfied with the level of profits realized by Delaware Investments from its relationships with the Fund and the Delaware Investments Family of Funds. ECONOMIES OF SCALE. The Trustees considered whether economies of scale are realized by Delaware Investments as the Fund's assets increase and the extent to which any economies of scale are reflected in the level of management fees charged. The Trustees took into account the standardized advisory fee pricing and structure approved by the Board and shareholders as part of a complex-wide shareholder meeting conducted in 1998/1999. At that time, Delaware Investments introduced breakpoints to account for management economies of scale. The Board noted that the fee under the Fund's management contract fell within the standard structure. The Board also noted that the Fund's assets exceeded the first breakpoint level. The Board believed that, given the extent to which economies of scale might be realized by the manager and its affiliates, the schedule of fees under the Investment Advisory Agreement provides a sharing of benefits with the Fund and its shareholders. 16 Delaware Investments(R) - ----------------------------------- A member of Lincoln Financial Group This semiannual report is for the information of Delaware Tax-Free Pennsylvania Fund shareholders, but it may be used with prospective investors when preceded or accompanied by a current prospectus for Delaware Tax-Free Pennsylvania Fund and the Delaware Investments Performance Update for the most recently completed calendar quarter.
