Stocks spent much of April retracing their gains, as higher interest rates and soaring energy prices overwhelmed sentiment. Then a brisk May rally left the Dow Industrials, the Standard and Poor's 500 Stock Index and the NASDAQ Composite slightly below year-end levels. With investors less welcoming of risk and the economy giving mixed signals, value stocks were more resilient than growth stocks. Large-capitalization stocks held up better than small- and mid-sized issues that might be seen as more vulnerable in an economic "soft patch," in the phrase of Federal Reserve Board Chairman Alan Greenspan. The possibility of slower growth notwithstanding, the Fed continued to raise short-term rates in an effort to head off damaging inflation. Bond returns were modestly negative overall early in the year, and fixed-income investors more risk-averse. High-yield and other corporate sectors retrenched after a run of stellar performance while Treasuries and mortgage-backed securities showed smaller declines. Long-term bond prices rose and their yields fell, suggesting that investors were not concerned about inflation and offering a boost to home buyers. Municipal revenue bonds trended higher against a backdrop of heavy new issuance by states and localities. Higher U.S. interest rates enhanced the dollar's appeal and brought a pause in its protracted fall. However, the stronger dollar meant muted returns for U.S. investors in overseas markets. Globally, economies rich in metals and other industrial commodities benefited from heavy demand. Meanwhile, growth in Japan may have stalled, and Europe's halting expansion ran afoul of political issues. We believe that the U.S. economy and corporate earnings will continue to grow at a moderate pace. Although oil prices had backed away from their record highs, steep energy costs and rising interest rates may hold investor attention for a while. Looking beyond present concerns, Pioneer's global investment experts continue to find stocks and bonds with attractive long-term potential for our domestic and international funds.

Current performance may be lower or higher than the performance data quoted. Performance data shown represents past performance. Past performance is no guarantee of future results. Investment return and market price will fluctuate, and your shares may trade below NAV, due to such factors as interest rate changes, and the perceived credit quality of borrowers. Total investment return does not reflect broker sales charges or commissions. All performance is for common shares of the Trust. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, shares of closed-end funds are sold in the open market through a stock exchange and frequently trade at prices lower than their NAV. NAV is total assets less total liabilities, which includes preferred shares, divided by the number of common shares outstanding. When NAV is lower than market price, dividends are assumed to be reinvested at the greater of NAV or 95% of the market price. When NAV is higher, dividends are assumed to be reinvested at market price. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Trust distributions or the redemption of Trust shares. Index comparison begins January 31, 2004. The Lehman Brothers Municipal Bond Index is a broad measure of the municipal bond market. The Standard & Poor's 500 Stock Index (the S&P 500) is a commonly used measure of the broad U.S. stock market. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or charges. You cannot invest directly in an Index. 4 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 5/31/05 -------------------------------------------------------------------------------- Investors in Pioneer Tax Advantaged Balanced Trust were rewarded during the six-month period ended May 31, 2005, as both municipal bonds and large-cap stocks produced positive returns. In the following interview, David Eurkus, portfolio manager for the Trust's fixed-income portion, and Walter Hunnewell, Jr., portfolio manager for the Trust's equity portion, discuss the Trust's investment strategy and outlook. Q: How did the Trust perform during the period? A: For the six-month period ended May 31, 2005, Pioneer Tax Advantaged Balanced Trust returned 7.08% at net asset value and 6.90% at market price. As of May 31, 2005, the Trust was selling at a discount of market price to net asset value of 12.6%. From November 30, 2004 through May 31, 2005, the Lehman Brothers Municipal Bond Index returned 3.51% and the S&P 500 Index returned 2.42%.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What was the investment environment like during the period? A: The economic expansion continued, raising concerns about the potential for accelerating inflation. In this environment, the Federal Reserve maintained its measured policy of periodically boosting the Federal funds rate by a quarter percentage point. (The Federal funds rate is the rate banks charge each other for overnight loans.) As a result of the Fed's actions, yields on short-term and intermediate-term bonds rose, but yields on long-term bonds declined, which increased their value as their prices went up. Concerns about rising interest rates, along with higher oil prices, were evident in the performance of the equity markets. While the S&P 500 Index was up 2.42%, stock prices fluctuated within a broad range, as investors assessed the impact that higher interest rates and oil prices would have on corporate profits. 5 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 5/31/05 (continued) -------------------------------------------------------------------------------- Q: What were the principal strategies used in managing the fixed-income portion of the Trust? A: On May 31, 2005, municipal securities accounted for 55% of portfolio assets. We primarily emphasized high-quality, investment-grade bonds, although we continued to maintain a 12.8% position in selected below investment-grade securities, which we believed were undervalued. The lower-quality securities helped the Trust maintain a relatively high level of income. They also added principal appreciation. At the end of the period, the credit quality breakdown of the fixed-income portion of the Trust was: AAA (26.4%); AA (10.3%); A (22.6%); BBB (27.0%); BB and lower (12.8%). The largest allocation of fixed-income assets was to insured bonds (22.8%), various revenue bonds (22.4%) and special revenue bonds (5.0%). The Trust was diversified across a variety of economic sectors. Health care/hospitals accounted for 31.1%, education 5.5%, housing 3.3%, pollution control 2.4%, transportation 4.0%, and water and sewer 1.5%. During the period, we maintained our hedging strategy, which was implemented early in 2004. At that time, short-term interest rates were at historically low levels, but long-term rates were relatively high. This situation allowed us to borrow funds at low short-term rates to invest in long-term municipal bonds. This leveraging strategy helped augment the Trust's income. On May 31, 2005, about 32% of the fixed-income portion of the Trust was leveraged. About 60% of the Trust's leverage is now hedged for four years. Q: What were the principal strategies used in managing the equity portion of the Trust? A: At the end of the period, about 45% of the portfolio was invested in equities. We focused on the highest yielding sectors of the market and on companies with long-term records of dividend payouts. Financials and utilities (38.3% and 30.5% of equity net assets, respectively) accounted for the largest sector allocations. Among equities, utilities were the biggest contributors to performance. Exelon, which benefited from its exposure to the nuclear industry at a time when oil prices were rising, made some of the biggest gains. Ameren also aided results. The company has made a number of opportunistic acquisitions of smaller utilities, and it 6 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- has exposure to coal-fired generation, which may benefit it in the future as deregulation continues. Q: What detracted from performance? A: Financial stocks held back performance, reflecting investor concerns that rising interest rates would have a negative impact on the earnings of financial institutions. General Motors also suffered because of a poor earnings outlook, and telecommunications company SBC Communications declined. Q: What is your outlook? A: Moving into the second half of 2005, we believe economic growth will continue at a moderate rate. We expect the Fed to continue raising interest rates at a measured pace and believe inflation will be held in check. This type of environment should be positive for municipal bonds. On the equity side, we expect corporate profit growth to be fairly strong, although less robust than in 2004. While high oil prices remain a factor in the equity market, we continue to find opportunities in companies that have long-term records of dividend payouts in the highest yielding areas of the market.

Organization and Significant Accounting Policies Pioneer Tax Advantaged Balanced Trust (the "Trust") was organized as a Delaware business trust on October 16, 2003. Prior to commencing operations on January 28, 2004, the Trust had no operations other than matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended, and the sale and issuance to Pioneer Funds Distributor, Inc., an affiliate of Pioneer Investment Management, Inc. ("PIM"), the Trust's investment adviser, a wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), of 6,981 shares of beneficial interest at an aggregate purchase price of $100,003. The investment objective of the Trust is to provide a high level of total after-tax return, including attractive tax-advantaged income. The Trust may invest in municipal securities with a broad range of maturities and credit ratings, including both investment grade and below investment grade municipal securities. The Trust may also invest in common stocks and preferred securities that pay tax-qualified dividends. In addition, the Trust may invest in other securities, including debt instruments, real estate investment trusts ("REITS") and equity securities, that generate income taxable at ordinary income rates, rather than long-term capital gain rates. The Trust invests in below investment grade (high-yield) debt securities. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. The Trust's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Trust to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Trust in preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: 28 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- A. Security Valuation Security transactions are recorded as of trade date. Debt securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Equity securities are valued at the last sale price on the principal exchange where they are traded. The values of interest rate swaps are determined by obtaining dealer quotations. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. The Trust may also use the fair value of a security, including a non U.S. security, when the closing market price on the principal exchange where the security is traded no longer accurately reflects the value of the security as of the close of the exchange. As of May 31, 2005, there were no securities fair valued. Temporary cash investments are valued at amortized cost. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Trust becomes aware of the ex-dividend data in the exercise of reasonable diligence. Discount and premium on debt securities are accreted or amortized daily, respectively, on an effective yield to maturity basis and are included in interest income. Interest income, including income on interest bearing cash accounts, is recorded on an accrual basis. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the source of the Trust's 29 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/05 (unaudited) (continued) -------------------------------------------------------------------------------- distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. At November 30, 2004, the Trust had a capital loss carryforward of $6,830,525 which will expire in 2012 if not utilized. The tax character of current year distributions paid will be determined at the end of the current fiscal year. The tax character of distributions paid to common and preferred shareowners during the period ended November 30, 2004 was as follows: -------------------------------------------------------------------------------- 2004 -------------------------------------------------------------------------------- Distributions paid from: Tax-Exempt income $ 9,413,848 Ordinary income 8,165,700 Long-term capital gain - ----------- $17,579,548 =========== -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at November 30, 2004. 2004 -------------------------------------------------------------------------------- Undistributed tax-exempt income $ 475,326 Undistributed ordinary income 412,584 Capital loss carryforward (6,830,525) Unrealized appreciation 15,371,827 ---------- Total $9,429,212 ========== -------------------------------------------------------------------------------- The difference between book basis and tax basis unrealized appreciation is primarily attributable to the difference between book and tax amortization methods for premiums and discounts on fixed income securities. C. Automatic Dividend Reinvestment Plan All common shareowners automatically participate in the Automatic Dividend Reinvestment Plan (the "Plan"), under which participants receive all dividends and capital gain distributions (collectively, "dividends") in full and fractional common shares of the Trust in 30 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- lieu of cash. Shareowners may elect not to participate in the Plan. Shareowners not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notifying Mellon Investor Services LLC, the agent for shareowners in administering the Plan (the "Plan Agent"), in writing prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Whenever the Trust declares a dividend on common shares payable in cash, participants in the Plan will receive the equivalent in common shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized common shares from the Trust or (ii) by purchase of outstanding common shares on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend, the net asset value per common share is equal to or less than the market price per share plus estimated brokerage trading fees ("market premium"), the Plan Agent will invest the dividend amount in newly issued common shares. The number of newly issued common shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per common share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per common share is greater than the market value ("market discount"), the Plan Agent will invest the dividend amount in common shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued common shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open-market purchases. Participating in the Plan does not relieve shareowners from any federal, state or local taxes which may be due on dividends paid in any taxable year. Shareowners holding Plan shares in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. 2. Management Agreement PIM manages the Trust's portfolio. Management fees are calculated daily at the annual rate of 0.60% of the Trust's average daily managed assets. "Managed assets" is the average daily value of the 31 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/05 (unaudited) (continued) -------------------------------------------------------------------------------- Trust's total assets minus the sum of the Trust's liabilities, which liabilities exclude debt related to leverage, short-term debt and the aggregate liquidation preference of any outstanding preferred shares. At May 31, 2005, $309,608 was payable to PIM related to management fees. In addition, under PIM's management and administration agreements, certain other services and costs are paid by PIM and reimbursed by the Trust. For the six months ended, the Trust recorded $16,715 in reimbursements and is included in "Administration fees and reimbursement" on the Statement of Operations. The Trust has retained Princeton Administrators, L.P., ("Princeton") an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, to provide certain administrative services to the Trust on its behalf. The Trust pays Princeton a monthly fee at an annual rate of 0.07% of the average daily value of the Trust's managed assets up to $500 million and 0.03% for average daily managed assets in excess of $500 million, subject to a minimum monthly fee of $10,000. Also, PIM has agreed for the first three years of the Trust's investment operations to limit the Trust's total annual expenses [excluding offering costs for common and preferred shares, interest expense, the cost of defending or prosecuting any claim or litigation to which the Trust is a party (together with any amount in judgment or settlement), indemnification expenses or taxes incurred due to the failure of the Trust to qualify as a regulated investment company under the Code or any other non-recurring or non-operating expenses] to 0.80% of the Trust's average daily managed assets. The dividend on any preferred shares is not an expense for this purpose. For the six months ended, May 31, 2005, the Trust's expenses were not reduced under such arrangements. 3. Transfer Agents Pioneer Investment Management Shareholder Services, Inc. ("PIMSS"), a wholly owned indirect subsidiary of UniCredito Italiano, through a sub-transfer agency agreement with Mellon Investor Services LLC, provides substantially all transfer agent and shareowner services related to the Trust's common shares at negotiated rates. Deutsche Bank Trust Company Americas is the transfer agent, registrar, dividend paying agent and redemption agent with respect to the Trust's Auction Market Preferred Shares ("AMPS"). The Trust pays 32 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Deutsche Bank Trust Company Americas an annual fee, as is agreed to from time to time by the Trust and Deutsche Bank Trust Company Americas, for providing such services. 4. Interest Rate Swaps The Trust may enter into interest rate swap transactions to attempt to protect itself from increasing dividend or interest expense on its leverage resulting from increasing short-term interest rates. The cost of leverage may rise with an increase in interest rates, generally having the effect of lower yields and potentially lower dividends to common shareowners. Interest rate swaps can be used to "lock in" the cost of leverage and reduce the negative impact that rising short-term interest rates would have on the Trust's leveraging costs. An interest rate swap is an agreement between two parties, which involves exchanging a floating rate and fixed rate interest payments for a specified period of time. Interest rate swaps involve the accrual of the net interest payments between the parties on a daily basis, with the net amount recorded within the unrealized appreciation/ depreciation of interest rate swaps on the Statement of Assets and Liabilities. Once the interim payments are settled in cash, at the pre-determined dates specified in the agreement, the net amount is recorded as realized gain or loss from interest rate swaps on the Statement of Operations. During the term of the swap, changes in the value of the swap are recognized as unrealized gains and losses by "marking-to market" the market value of the swap based on values obtained from dealer quotations. When the swap is terminated, the Trust will record a realized gain or loss equal to the difference, if any, between the proceeds from (or cost of) closing the contract and the cost basis of the contract. The Trust is exposed to credit risk in the event of non-performance by the other party to the interest rate swap. However, at May 31, 2005 the Trust does not anticipate non-performance by any counterparty. Risk may also arise with regard to market movements in the value of the swap arrangement that do not exactly offset the changes in the related dividend requirement or interest expense on the Trust's leverage. Under the terms of the agreement entered into by the Trust, the Trust receives a floating rate of interest and pays a fixed rate of interest for the term. Details of the swap agreement outstanding as of May 31, 2005 were as follows: 33 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/05 (unaudited) (continued) -------------------------------------------------------------------------------- -------------------------------------------------------------------------------------- Termination Notional Fixed Unrealized Counterparty Date Amount (000) Rate Floating Rate Appreciation ------------- ----------- ------------ ------ ------------- ------------ UBS AG Sept. 1, 2009 $106,000 2.855% 1 month BMA $792,336 -------------------------------------------------------------------------------------- 5. Trust Shares There are an unlimited number of common shares of beneficial interest authorized. Of the 28,706,981 common shares of beneficial interest outstanding at May 31, 2005, PIM owned 6,981 shares. Transactions in common shares of beneficial interest for the six months ended May 31, 2005 and the period from January 28, 2004 (commencement of operations) to November 30, 2004 were as follows: -------------------------------------------------------------------------------- 2005 2004 -------------------------------------------------------------------------------- Shares issued in connection with initial public offering - 25,600,000 Shares issued from underwriters' over-allotment option exercised - 3,100,000 ---------- ---------- Net increase in shares outstanding - 28,700,000 Shares outstanding at beginning of period 28,706,981 6,981 ---------- ---------- Shares outstanding at end of period 28,706,981 28,706,981 ========== ========== The Trust may classify or reclassify any unissued common shares of beneficial interest into one or more series of preferred shares of beneficial interest. As of May 31, 2005, there were 7,050 AMPS as follows: Series T7-2,350, Series F7-2,350 and Series TH28-2,350. Dividends on Series T7 and Series F7 are cumulative at a rate which is reset every seven days based on the results of an auction. Dividends on Series TH28 are also cumulative at a rate reset every 28 days based on the results of an auction. Dividend rates ranged from 2.05% to 3.36% during the six months ended May 31, 2005. The Trust may not declare dividends or make other distributions on its common shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred shares would be less than 200%. The AMPS are redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared. The AMPS 34 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Trust as set forth in the Agreement and Declaration of Trust are not satisfied. The holders of AMPS have voting rights equal to the holders of the Trust's common shares (one vote per share) and will vote together with holders of the common shares as a single class. However, holders of AMPS are also entitled to elect two of the Trust's Trustees. In addition, the Investment Company Act of 1940, as amended, requires that along with approval by shareowners that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class, would be required to (a) adopt any plan of reorganization that would adversely affect the preferred shares and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. 6. Subsequent Events Subsequent to May 31, 2005, the Board of Trustees of the Trust declared a dividend from undistributed net investment income of $0.0687 per common share payable June 30, 2005, to common shareowners of record on June 15, 2005. For the period June 1, 2005 to June 30, 2005, dividends declared on preferred stock totaled $418,441 in aggregate for the three outstanding preferred share series. ADDITIONAL INFORMATION (unaudited) During the period, there have been no material changes in the Trust's investment objective or fundamental policies that have not been approved by the shareowners. There have been no changes in the Trust's charter or By-Laws that would delay or prevent a change in control of the Trust which have not been approved by the shareowners. There have been no changes in the principal risk factors associated with investment in the Trust. There have been no changes in the persons who are primarily responsible for the day-to-day management of the Trust's portfolio. 35 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/05 (unaudited) (continued) -------------------------------------------------------------------------------- Notice is hereby given in accordance with Section 23(C) of the Investment Company Act of 1940 that the Trust may purchase, from time to time, its common shares in the open market. 36 Pioneer Tax Advantaged Balanced Trust -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS Trustees Officers John F.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.

N/A (f) If greater than 50 percent, disclose the percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees. N/A (g) Disclose the aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for each of the last two fiscal years of the registrant. The Fund's independent auditor, Ernst & Young LLP ("E&Y"), has advised the Securities and Exchange Commission, the Public Company Accounting Oversight Board, and the Audit Committee of the Fund's Board of Trustees that certain non-audit work performed by E&Y's China affiliate raised questions regarding E&Y's independence with respect to its performance of audit services for the Fund. In July 2004, E&Y became aware that member firms in China ("E&Y China") provided certain tax services to offices of UniCredito Italiano, S.p.A. ("UCI"), a member of the Fund's Investment Company Complex. The services included receipt and disbursement of monies transferred to E&Y China by UCI in payment of individual expatriate income taxes due on returns prepared by E&Y China for certain UCI employees located in China from October 1998 to May 2003. E&Y became auditors of the Fund in May 2002. These expatriate tax services were discontinued in May 2003. The fees received by E&Y China for all such services totaled $3,685.
