Pioneer Tax Advantaged Balanced Trust

--------------------------------------------------------------------------------
LETTER TO SHAREOWNERS 5/31/05
--------------------------------------------------------------------------------

Dear Shareowner,
--------------------------------------------------------------------------------
U.S. equity markets stumbled early in the year before advancing to three-year
highs in March. 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.

This period was like all others; different classes of investments delivered
different returns. That's why allocating your portfolio across several
investment types is one way to seek wider opportunities. Pioneer's disciplined
approach and growing range of products are designed to help you achieve this

Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent month-end
performance results. 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.

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%.

    Call 1-800-225-6292 or visit www.pioneerfunds.com for the most recent
    month-end performance results. Current performance may be lower or higher
    than the performance data quoted.

    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

--------------------------------------------------------------------------------
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.

Pioneer Tax Advantaged Balanced Trust

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 5/31/05 (unaudited)
--------------------------------------------------------------------------------

1. 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

--------------------------------------------------------------------------------

    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:

    The following shows the components of distributable earnings on a federal
    income tax basis at November 30, 2004.

   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

--------------------------------------------------------------------------------
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

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

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

                                                ==========         ==========


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.

period covered by the report, to a provision of its code of ethics that applies
to the registrant's principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions, regardless of whether these individuals are employed by the
registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must

covered by this report.

(d) If the registrant has, during the period covered by the report, granted a

of the waiver, the name of the person to whom the waiver was granted, and the
date of the waiver.

Not applicable.

(e) If the registrant intends to satisfy the disclosure requirement under
paragraph (c) or (d) of this Item regarding an amendment to, or a waiver from,
a provision of its code of ethics that applies to the registrant's principal

        or persons performing similar functions, as an exhibit to its annual
        report on this Form N-CSR;

        (2) Post the text of such code of ethics on its Internet website and

 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.

--------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

--------------------------------------------------------------------------------


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

    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.

The Fund's Audit Committee and E&Y have 
discussed the matter, including the nature of the 
services provided, the personnel involved in 
providing the services and the fees received by 
E&Y for performing the services.  E&Y has informed 
the Audit Committee that based on its internal reviews 
and the de minimis nature of the services provided and 
fees received, it does not believe its independence 
with respect to the Fund has been impaired.

N/A


(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser 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 investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.
