LETTER TO SHAREOWNERS 12/31/04
================================================================================

Dear Shareowner,
- --------------------------------------------------------------------------------
After three calendar quarters of listless performance, U.S. equity markets
improved strongly late in the year. Anxiety over energy prices, international
tensions and the falling American dollar had held the markets back, but
uneasiness about the presidential election was the principal source of investor
hesitation. The election went smoothly, the result was decisive, and the ensuing
rally pushed major indices into the black for the second year running. However,
returns trailed 2003's levels. Small capitalization companies outperformed large
cap issues for the sixth consecutive year. Markets overseas were generally
buoyant: commodity-rich nations saw surging demand for copper, gold, lumber and
other materials, with much of their output destined to feed China's vast
economic appetite.

Bond investors focused on longer-term issues. Reflecting the risk aversion that
favored small cap stocks, high-yield bonds were the strongest performers, while
higher quality issues, including U.S. Treasury issues, scored more modest gains.
Municipal bond returns were generally favorable as well; economic growth spurred
rising tax revenues, putting many issuers into surplus for the first time in
years.

A measured pace of growth seems in store for the U.S. economy, which generated
2.2 million jobs after years of employment declines. By the end of September,
the economy had tallied twelve straight up quarters and the nation's annualized
growth rate stood at a respectable four percent. We believe this rate of
expansion is enough to sustain growth without provoking the Federal Reserve
Board into aggressive interest rate hikes aimed at calming inflation.

Welcome to former Safeco fund shareholders

With this report, we also would like to acknowledge the investors in former

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.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not reflect
the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a
1% sales charge, your returns would be lower than those shown above. All results
are historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information. The performance table
and graph do not reflect the deduction of fees and taxes that a shareowner would
pay on Fund distributions or the redemption of Fund shares.

Performance for periods prior to the inception of Y shares reflects the NAV
performance of the Fund's A shares. The performance does not reflect differences
in expenses, including the Rule 12b-1 fees applicable to A shares. Since fees
for A shares are generally higher than those of Y shares, the performance shown
for Y shares prior to their inception would have been higher. Class A shares are
used as a proxy from 10/31/78 to 9/20/01. Class Y shares are not subject to
sales charges and are available for limited groups of eligible investors,
including institutional investors. All results are historical and assume the
reinvestment of dividends and capital gains. Other share classes are available
for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a

Certain Pioneer funds (the "Funds") issued Investor Class shares in connection
with the reorganization of Safeco mutual funds. The Funds are not offering
additional Investor Class shares except in connection with the reinvestment of

shares of the Funds, whenever issued, convert to Class A shares of their
respective Funds on December 10, 2006. Investor Class shares are not subject to
sales charges.

COMPARING ONGOING FUND EXPENSES
================================================================================

As a shareowner in the Fund, you incur two types of costs:

(1) ongoing costs, including management fees, distribution and/or service
    (12b-1) fees, and other Fund expenses; and

(2) transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (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 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables

Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.  Divide your account value by $1,000
    Example: an $8,600 account value [divide] $1,000 = 8.6

2.  Multiply the result in (1) above by the corresponding share class's number
    in the third row 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 table below 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 tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads).. Therefore, the table below 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 transaction costs were included, your
costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION 12/31/04
================================================================================

As the domestic economy showed evidence of a sustained recovery during the
second half of 2004, the U.S. Federal Reserve continued to raise short-term
interest rates gradually to contain the risk of inflation and keep the economy
in check. The fixed-income market reacted favorably to the Fed's series of
measured increases in the Fed funds rate, with the yields of longer-term
Treasuries actually declining modestly. Meanwhile corporate bonds and mortgages
continued to outperform Treasuries as investors sought out higher-yielding
investments in an environment of low, by historical standards, interest rates.
In the following discussion, Kenneth J. Taubes discusses the factors that
influenced Pioneer Bond Fund's performance during the six months. Mr. Taubes,
Director of Pioneer's Fixed Income Group, oversees the team responsible for
daily management of the Fund.

Q: How did the Fund perform during six months ended December 31, 2004?

A: Pioneer Bond Fund performed well, outpacing its benchmark as well as the
   competitive funds average. For the six-month period, the Fund's Class A
   shares returned 4.92%, at net asset value. During the same six months, the
   Lehman Brothers Aggregate Bond Index returned 4.18%, while the average total
   return of the 224 funds in Lipper's Corporate Debt A-Rated Bond Fund category
   was also 4.18%. On December 31, 2004, the standardized 30-day SEC Yield on
   Class A shares was 4.00%.

   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 factors affected Fund performance?

A: During a period in which investors sought out yield, the Fund held to its
   emphasis on sectors with yield advantages over Treasuries, corporate bonds
   and mortgage-backed securities. Both corporate bonds and mortgage securities
   outperformed Treasuries, with high-yield corporate securities turning in the
   best performance of all sectors of the domestic bond market. Despite rising
   short-term rates, the yields of longer maturity Treasuries were relatively
   stable, and investors sought out securities with yield advantages


                                                                              11

   over Treasuries. Against a backdrop of a strengthening economy, corporations
   generated additional cash flow, which improved the overall credit quality of
   corporate securities and further encouraged investments in both high-yield
   and investment-grade corporate debt.

   Our emphasis on high-yield and investment-grade corporate bonds as well as
   mortgage securities helped support Fund performance throughout the six
   months. At the end of the six-month period, about 55% of assets were invested
   in mortgage securities and about 40% were invested in corporate debt,
   including almost 15% high-yield bonds. We reduced our high-yield positions
   slightly in the final quarter of the year. As we did so, we increased our
   investments in mortgages, which offered yields competitive with
   investment-grade corporates but with higher quality. Overall average credit
   quality of the portfolio was raised slightly during the period from A to A+.

   Less significant but also helpful was our decision to keep the Fund's
   sensitivity to interest-rate changes -- as measured by duration -- either
   neutral or slightly longer than the benchmark Lehman Brothers Aggregate Bond
   Index. In an environment of stable to slightly-declining market interest
   rates, this strategy tended to benefit performance. On December 31, 2004, the
   Fund's average effective duration was a somewhat shorter 3.99 years.

Q: What were some of the individual holdings that most influenced portfolio
   performance?

A: Among the high-yield holdings that helped performance were the bonds of two
   steel companies: International Steel, which we sold to take profits before
   the period ended, and ISPAT Inland ULC, which were upgraded in credit rating
   after the company was acquired by a Dutch corporation. Other bonds which
   appreciated strongly in price were those of financial service corporates
   Allmerica Financial, E-Trade and Odyssey Re.

   Detracting from results were insurance company Provident, whose bond prices
   slipped amid controversy over the New York attorney general's investigation
   of industry practices, Toys "R" Us, which announced restructuring plans, and
   Intelsat, a satellite company that withdrew plans for an initial public stock
   offering.

Q: What is your investment outlook?

A: We anticipate that the Federal Reserve will continue to raise the Fed funds
   rate at a gradual pace during 2005. The fixed-income market already has
   anticipated, in current bond prices, a series of further increases that would
   bring the Fed funds rate from 2.25% to near 3.5% by the end of the year. We
   believe the market rates of longer-term and intermediate-term securities
   already are close to being fairly valued. As a result, we anticipate that the
   yield curve -- which measures the relationship between short-term and
   longer-term interest rates -- likely will flatten during the year as
   short-term rates move up.

   In general, valuations of corporate securities appear relatively high by
   historical standards, but they probably are justified given the strong
   economic fundamentals both in the United States and throughout the globe.
   Strengthening economies are now helping companies across all sectors,
   resulting in improved cash flows and corporate profits. In this environment,
   we think corporate bonds should perform well, consistent with their yield
   advantage over Treasuries. As a result, we will continue to look for
   opportunities in the corporate sector. However, we expect to also put greater
   emphasis on mortgage securities, which offer virtually the same yields as
   investment-grade corporate debt but have the advantage of higher credit
   ratings.




   Investments in high yield or lower-rated securities are subject to
   greater-than-average risk. When interest rates rise, the prices of fixed
   income securities in the Fund will generally fall. Conversely, when interest
   rates fall the prices of fixed-income securities in the Fund will generally
   rise. The portfolio may invest in mortgage-backed securities, which during
   times of fluctuating interest rates may increase or decrease more than other
   fixed-income securities. Mortgage-backed securities are also subject to
   pre-payments. Investments in the Fund are subject to possible loss due to the
   financial failure of underlying securities and their inability to meet their
   debt obligations.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the Fund's historical or future performance
   are statements of the opinion of Fund management as of the date of this
   report. These statements should not be relied upon for any other purposes.
   Past performance is no guarantee of future results, and there is no guarantee
   that market forecasts discussed will be realized.

(a) As a result of a change in accounting principle, the effect due to mandatory
    accretion of discounts and amortization of premiums on debt securities
    resulted in a reduc- tion of net investment income of $0.02 per share, an
    increase in net realized and unrealized gain (loss) on investments of $0.02
    per share, and the ratio of net invest- ment income to average net assets
    decreased by 0.18%.

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

1. Organization and Significant Accounting Policies

Pioneer Bond Fund (the Fund) is a Delaware statutory trust registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is to seek current income
consistent with preservation of capital.

The Trustees have authorized the issuance of six classes of shares of the Fund.
The Fund offers six classes of shares designated as Class A, Class B, Class C,
Investor Class, Class R, and Class Y shares. Class R shares were first publicly
offered April 1, 2003. Investor Class shares were first publicly offered on
December 10, 2004. The Fund is not offering additional Investor Class shares
except in connection with the reinvestment of dividends on the Fund's
Outstanding Investor Class shares. Each class of shares represents an interest
in the same portfolio of investments of the Fund and has equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distributions fees and has exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B, Class C, and Class R shareowners, respectively. There is no
distribution plan for Class Y shares and Investor Class shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
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 Fund in the
preparation of its financial statements, which are consistent with those
policies generally accepted in the investment company industry:

A. Security Valuation

   Security transactions are recorded as of trade date. 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. Securities for which
   there are no other readily available valuation methods are valued at their
   fair values as


                                                                              43


Pioneer Bond Fund

================================================================================
NOTES TO FINANCIAL STATEMENTS 12/31/04 (unauditded)                  (continued)
================================================================================

   determined by, or under the direction of the Board of Trustees. At December
   31, 2004 there were no securities fair valued. Principal amounts of
   mortgage-backed securities are adjusted for monthly paydowns. Temporary cash
   investments are valued at amortized cost.

   All discounts/premiums on debt securities are accreted/amortized for
   financial reporting purposes over the life of the respective securities, and
   are included in interest income. Market discount and premium are accreted or
   amortized daily. Premiums and discounts related to certain mortgage-backed
   securities are amortized or accreted in proportion to the underlying monthly
   paydowns. Interest income is recorded on the 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 Fund'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 sources of the Fund's 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.

   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
   during the year ended December 31, 2004 was as follows:



- -----------------------------------------
                                   2004
- -----------------------------------------
                           
  Distributions paid from:
  Ordinary income             $13,862,071
  Long-term capital gain                -
                              -----------
  Total                       $13,862,071
                              -----------
=========================================

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

   The following shows the components of distributable earnings on a federal
   income tax basis at December 31, 2004.



- ------------------------------------------------
                                       2004
- ------------------------------------------------
                                 
  Undistributed ordinary income     $   881,220
  Dividends payable                 $  (229,477)
  Capital loss-carryforward         $(6,403,162)
  Unrealized appreciation           $ 2,826,845
                                    -----------
  Total                             $(2,924,574)
                                    -----------
================================================


   The difference between book basis and tax-basis unrealized appreciation is
   attributable to the tax deferral of losses on wash sales and the tax
   treatment of amortization.

C. Fund Shares

   The Fund records sales and repurchases of its shares as of trade date.
   Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund
   and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.,
   (UniCredito Italiano), earned $25,658 in underwriting commissions on the sale
   of Class A shares during the six months ended December 31, 2004.

D. Class Allocations

   Distribution fees are calculated based on the average daily net asset value
   attributable to Class A, Class B, Class C, and Class R shares of the Fund,
   respectively. Class Y and Investor Class shares are not subject to a
   distribution plan. Shareowners of each class share all expenses and fees paid
   to the transfer agent, Pioneer Investment Management Shareholder Services,
   Inc. (PIMSS), for its services, which are allocated based on the number of
   accounts in each class and the ratable allocation of related out-of-pocket
   expenses (see Note 3). Income, common expenses, and realized and unrealized
   gains and losses are calculated at the Fund level and allocated daily to each
   class of shares based on the respective percentage of adjusted net assets at
   the beginning of the day.

   The Fund declares as daily dividends substantially all of its net investment
   income. All dividends are paid on a monthly basis. Short-term capital gain
   distributions, if any, may be declared with the daily dividends.
   Distributions to shareowners are recorded as


                                                                              45


Pioneer Bond Fund

================================================================================
NOTES TO FINANCIAL STATEMENTS 12/31/04 (unauditded)                  (continued)
================================================================================

   of the ex-dividend date. Distributions paid by the Fund with respect to each
   class of shares are calculated in the same manner, at the same time, and in
   the same amount, except that Class A, Class B, Class C, Investor Class, Class
   R and Class Y shares can bear different transfer agent and distribution fees.

E. Repurchase Agreements

   With respect to repurchase agreements entered into by the Fund, the value of
   the underlying securities (collateral), including accrued interest received
   from the counterparties, is required to be at least equal to or in excess of
   the value of the repurchase agreement at the time of purchase. The collateral
   for all repurchase agreements is held in safekeeping in the customer-only
   account of the Fund's custodian, or subcustodians. The Fund's investment
   adviser, Pioneer Investment Management, Inc. (PIM), is responsible for
   determining that the value of the collateral remains at least equal to the
   repurchase price.

F. Securities Lending

   The Fund lends securities in its portfolio to certain broker-dealers or other
   institutional investors, with the Fund's custodian acting as the lending
   agent. When entering into a loan, the Fund receives collateral, which is
   maintained by the custodian and earns income in the form of negotiated
   lenders' fees. The Fund also continues to receive interest or payments in
   lieu of dividends on the securities loaned. Gain or loss on the fair value of
   the loaned securities that may occur during the term of the loan will be for
   the account of the Fund. The loans are secured by collateral of at least 102%
   at all times, of the fair value of the securities loaned. The amount of the
   collateral will be adjusted daily to reflect any price fluctuation in the
   value of loaned securities. The Fund has the right under the lending
   agreements to recover the securities on loan from the borrower on demand. The
   Fund invests cash collateral in the Securities Lending Investment Fund, which
   is managed by Brown Brothers Harriman & Co., the Fund's custodian.


2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. Management fees are calculated daily at the annual rate of
0.50% of the Fund's average daily net assets. In


46


Pioneer Bond Fund

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

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

addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting, and insurance
premiums, are paid by the Fund. At December 31, 2004, $119,533 was payable to
PIM related to management fees, administrative costs and certain other
services, and is included in due to affiliates.

Through December 10, 2006, PIM has agreed not to impose all or a portion of its
management fee and to assume other operating expenses (excluding taxes,
commissions, interest and extraordinary expenses) of the Fund to the extent
necessary to limit Investor Class expenses to 0.74% of the average daily net
assets attributable to Investor Class shares.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Fund at
negotiated rates. Included in due to affiliates is $99,738 in transfer agent
fees payable to PIMSS at December 31, 2004.


4. Distribution and Service Plans

The Fund adopted a Plan of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, Class C Plan and Class R Plan) in accordance with
Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan,
the Fund pays PFD a service fee of up to 0.25% of the average daily net assets
attributable to Class A shares in reimbursement of its actual expenditures to
finance activities primarily intended to result in the sale of Class A shares.
Pursuant to the Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of
the average daily net assets attributable to each class of shares. The fee
consists of a 0.25% service fee and a 0.75% distribution fee paid as
compensation for personal services and/or account maintenance services or
distribution services with regard to Class B and Class C shares. Pursuant to
the Class R Plan, the Fund pays PFD 0.50% of the average daily net assets
attributable to Class R shares for distribution services. Included in due to
affiliates is $108,525 in distribution fees payable to PFD at December 31,
2004. The Fund also has adopted a separate service plan for Class R shares
(Service Plan). The Service Plan authorizes the Fund to pay securities dealers,
plan administrators or other service organizations that agree to


                                                                              47


Pioneer Bond Fund

================================================================================
NOTES TO FINANCIAL STATEMENTS 12/31/04 (unauditded)                  (continued)
================================================================================

provide certain services to retirement plans or plan participants holding shares
of the Fund a service fee of up to 0.25% of the Fund's average daily net assets
attributable to Class R shares held by such plans.

In addition, redemptions of Class A, Class B, Class C and Class R shares may be
subject to a contingent deferred sales charge (CDSC). Effective February 1, 2004
a CDSC of 1.00% may be imposed on redemptions of certain net asset value
purchases of Class A shares within 18 months of purchase (12 months for shares
purchased prior to February 1, 2004). Effective December 1, 2004, Class B shares
that are redeemed within five years of purchase are subject to a CDSC at
declining rates beginning at 4.00%, based on the lower of cost or market value
of shares being redeemed. Shares purchased prior to December 1, 2004 remain
subject to the CDSC in effect at the time those shares were purchased.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%. Redemptions of Class R shares within 18 months of purchase were
subject to a CDSC of 1.00%. Effective July 1, 2004 the CDSC on Class R shares
was eliminated. Proceeds from the CDSCs are paid to PFD. For the six months
ended December 31, 2004, $71,576 in CDSCs were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended December 31, 2004, the Fund's
expenses were reduced by $1,945 under such arrangements.

6. Merger Information

On December 8, 2004, beneficial owners of Safeco Intermediate Term Bond Fund
(one of the series that comprised Safeco Taxable Bond Trust) approved a
proposed Agreement and Plan of Reorganization that provided for the merger
listed below. This tax-free reorganization was accomplished on December 10,
2004, by exchanging all of Safeco's net assets for Investor Class shares, based
on the Fund's Class A shares' ending net asset value. The following charts show
the details of the reorganizations as of that closing date ("Closing Date"):

 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 recognizes 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 recognizes 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.

                 firm, the scope of the Audit

- --------------------------------------------------------------------------------
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"), recently 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 has 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.  The Committee
continues to review the facts and circumstances
surrounding the matter, including the issue of
whether the monies transferred for employees' taxes
were de facto monies due the employees for tax
payments rather than monies belonging to UCI.
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.





(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.
