Percentages indicated are based on net assets of $195,375,577.

(a) Represents cost for financial reporting purposes and differs from market
    value by unrealized appreciation (depreciation) of securities as follows:

</Table>

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Non-income producing securities.

(c) Investment in affiliate.

Percentages indicated are based on net assets of $114,896,709.

(a) Represents cost for financial reporting purposes and differs from market
    value by unrealized appreciation (depreciation) of securities as follows:

<Table>

</Table>

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Non-income producing securities.

(c) Investment in affiliate.

    value by unrealized appreciation (depreciation) of securities as follows:

</Table>

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Non-income producing securities.

(c) Investment in affiliate.

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Non-income producing securities.

(c) Investment in affiliate.

(d) Security exempt from registration under Rule 144A of the Securities Act of
    1933. These securities may be resold in transactions exempt from
    registration, normally to qualified institutional buyers.

The Fund invests in securities whose value is derived from an underlying pool of
mortgages or consumer loans. Descriptions of certain collateralized mortgage
obligations are as follows:

  Inverse Floaters (IF) represent securities that pay interest at a rate that
  increases (decreases) with a decline (increase) in a specified index.

  Principal Only (PO) represents the right to receive the principal portion only
  on an underlying pool of mortgage loans. The market value of these securities
  is extremely volatile in response to changes in market interest rates. As
  prepayments on the underlying mortgages of these securities increase, the
  yield on these securities increases.

*  The interest rate for this variable rate note, which will change
   periodically, is based on prime rates or an index of market rates. The rate
   reflected on the Schedule of Portfolio of Investments is the rate in effect
   as of June 30, 2004.

(a) Represents cost for financial reporting purposes and differs from market

</Table>

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Security exempt from registration under Rule 144A of the Securities Act of
    1933. These securities may be resold in transactions exempt from
    registration, normally to qualified institutional buyers.

(c) Investment in affiliate.

    GO -- General Obligations

The Fund invests in securities whose value is derived from an underlying pool of
mortgages or consumer loans. Descriptions of certain collateralized mortgage
obligations are as follows:

  Inverse Floaters (IF) represent securities that pay interest at a rate that
  increases (decreases) with a decline (increase) in a specified index.

  Interest Only (IO) represents the right to receive the monthly interest
  payment on an underlying pool of mortgage loans. The face amount shown
  represents the par value on the underlying pool. The yields on these
  securities are generally higher than prevailing market yields on other
  mortgage-backed securities because their cash flow patterns are more volatile
  and there is a greater risk that the initial investment will not be fully
  recouped. These securities are subject to accelerated principal paydowns as a
  result of prepayment or refinancing of the underlying pool of mortgage
  instruments. As a result, interest income may be reduced considerably.

  High Coupon Bonds (HB) (a.k.a. "IOettes") represent the right to receive
  interest payments on an underlying pool of mortgages with similar risks as
  those associated with IO securities. Unlike IOs the owner also has the right
  to receive a very small portion of principal. The high interest rate results
  from taking interest payments from other classes in the REMIC trust and
  allocating them to the small principal of the HB class.

  Principal Only (PO) represents the right to receive the principal portion only
  on an underlying pool of mortgage loans. The market value of these securities
  is extremely volatile in response to changes in market interest rates. As
  prepayments on the underlying mortgages of these securities increase, the
  yield on these securities increases.

*  The interest rate for this variable rate note, which will change
   periodically, is based on prime rates or an index of market rates. The rate
   reflected on the Schedule of Portfolio of Investments is the rate in effect
   as of June 30, 2004.

See notes to financial statements.

Aggregate cost for federal income tax purposes differs from cost for financial
reporting purposes by less than 2% of net assets and is therefore considered
substantially the same.

(b) Investment in affiliate.

ONE GROUP INVESTMENT TRUST GOVERNMENT BOND PORTFOLIO
- --------------------------------------------------------------------------------

SCHEDULE OF PORTFOLIO INVESTMENTS, CONTINUED
(UNAUDITED)

The Fund invests in securities whose value is derived from an underlying pool of
mortgages or consumer loans. Descriptions of certain collateralized mortgage
obligations are as follows:

  Inverse Floaters (IF) represent securities that pay interest at a rate that
  increases (decreases) with a decline (increase) in a specified index.

  Interest Only (IO) represents the right to receive the monthly interest
  payment on an underlying pool of mortgage loans. The face amount shown
  represents the par value on the underlying pool. The yields on these
  securities are generally higher than prevailing market yields on other
  mortgage-backed securities because their cash flow patterns are more volatile
  and there is a greater risk that the initial investment will not be fully
  recouped. These securities are subject to accelerated principal paydowns as a
  result of prepayment or refinancing of the underlying pool of mortgage
  instruments. As a result, interest income may be reduced considerably

  Principal Only (PO) represents the right to receive the principal portion only
  on an underlying pool of mortgage loans. The market value of these securities
  is extremely volatile in response to changes in market interest rates. As
  prepayments on the underlying mortgages of these securities increase, the
  yield on these securities increases.

* The interest rate for this variable rate note, which will change periodically,
  is based on prime rates or an index of market rates. The rate reflected on the
  Schedule of Portfolio of Investments is the rate in effect as of June 30,
  2004.

ONE GROUP INVESTMENT TRUST            SEMI-ANNUAL REPORT           June 30, 2004

INVESTMENT TRUST SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

NOTES TO FINANCIAL STATEMENTS
(UNAUDITED)

1. ORGANIZATION:

   One Group Investment Trust (the "Trust") is registered under the Investment
   Company Act of 1940, as amended (the "1940 Act"), as an open-end investment
   company established as a Massachusetts business trust. The accompanying
   financial statements and financial highlights are those of the Mid Cap Growth
   Portfolio, the Mid Cap Value Portfolio, the Diversified Mid Cap Portfolio,
   the Large Cap Growth Portfolio, the Diversified Equity Portfolio, the Equity
   Index Portfolio, the Balanced Portfolio, the Bond Portfolio and the
   Government Bond Portfolio, (individually a "Portfolio", collectively the
   "Portfolios").

   Under the Trust's organizational documents, its officers and trustees are
   indemnified against certain liabilities arising out of the performance of
   their duties to the Trust. In addition, in the normal course of business, the
   Trust enters into contracts with their vendors and others that provide for
   general indemnifications. The Trust's maximum exposure under these
   arrangements is unknown as this would involve future claims that may be made
   against the Trust.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

   The following is a summary of significant accounting policies followed by the
   Trust in preparation of its financial statements. The policies are in
   conformity with U.S. generally accepted accounting principles. The
   preparation of financial statements requires management to make estimates and
   assumption that affect the reported amounts of assets and liabilities at the
   date of the financial statements and the reported amounts of income and
   expenses for the period. Actual results could differ from those estimates.

     SECURITY VALUATION

     Listed securities are valued at the closing prices as determined by the
     primary exchange where such securities are traded. Unlisted securities or
     listed securities for which latest sales prices are not available are
     valued at the mean of the latest bid and ask price on the principal
     exchange market or where such securities are normally traded. Corporate
     debt securities, debt securities issued by the U.S. Treasury or U.S.
     government agency (other than short-term investments maturing in less than
     61 days), and municipal securities are valued on the basis of valuations
     provided by dealers or by an independent pricing service approved by the
     Board of Trustees. Short-term investments maturing in less than 61 days are
     valued at amortized cost, which approximates market value. Futures
     contracts are valued at the settlement price established each day by the
     board of trade or exchange on which they are traded. Options traded on an
     exchange are valued using the last sale price or, in the absence of a sale,
     the mean of the latest bid and ask prices. Options traded over-the-counter
     are valued using dealer-supplied valuations. Investments for which the
     above valuation procedures are inappropriate, when valuations are not
     readily available or when valuations are deemed not to reflect fair value
     are stated at fair value as determined in good faith under procedures
     approved by the Board of Trustees.

     FINANCIAL INSTRUMENTS

     Investing in financial instruments such as futures and indexed securities
     involves risk in excess of the amounts reflected in the Statements of
     Assets and Liabilities. The face or contract amounts reflect the extent of
     the involvement the Portfolios have in the particular class of instrument.
     Risks associated with these instruments include an imperfect correlation
     between the movements in the price of the instruments and the price of the
     underlying securities and interest rates, and an illiquid secondary market
     for the instruments or inability of counterparties to perform under the
     terms of the contract. The Portfolios enter into these contracts primarily
     as a means to hedge against adverse fluctuation in the value of securities
     held or planned to be purchased by the Portfolios.

     FUTURES CONTRACTS

     The Portfolios may enter into futures contracts for the delayed delivery of
     securities at a fixed price at some future date or for the change in the
     value of a specified financial index over a predetermined time period.

     Cash or securities are deposited with brokers in order to maintain a
     position. Subsequent payments made or received by a Portfolio based on the
     daily change in the market value of the position are recorded as unrealized
     appreciation or depreciation until the contract is closed out, at which
     time the appreciation or depreciation is realized.

Continued


                                                                              61

INVESTMENT TRUST SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

NOTES TO FINANCIAL STATEMENTS, CONTINUED
(UNAUDITED)

     Upon entering into a futures contract, the Portfolios are required to
     pledge to the broker an amount of cash, U.S. government securities or other
     assets, equal to a certain percentage of the contract amount. This is known
     as the initial margin deposit. Subsequent payments, known as variation
     margin, are made or received by the Funds each day, depending on the daily
     fluctuations in fair value of the underlying index. The Funds recognize a
     gain or loss equal to the variation margin.

     The Funds did not hold any futures as of June 30, 2004.

     INDEXED SECURITIES

     The Portfolios, other than Equity Index Portfolio, may invest in indexed
     securities whose value is linked either directly or inversely to changes in
     foreign currency, interest rates, commodities, indices or other reference
     instruments. Indexed securities may be more volatile than the referenced
     instrument itself, but any loss is limited to the amount of the original
     investment.

     REPURCHASE AGREEMENTS

     The Portfolios may invest in repurchase agreements with institutions that
     are deemed by Banc One Investment Advisors Corporation (the "Advisor") to
     be of good standing and creditworthy under guidelines established by the
     Board of Trustees. Each repurchase agreement is valued at cost and the
     underlying collateral is valued at or above the value of the repurchase
     agreement plus accrued interest. The Portfolio requires that the collateral
     received in a repurchase agreement transaction be transferred to a
     custodian in a manner sufficient to enable the Portfolio to obtain the
     collateral in the event of a counterparty default. If the counterparty
     defaults and the fair value of the collateral declines, realization of the
     collateral by the Portfolios may be delayed or limited. The Portfolios,
     along with certain other affiliates of the Portfolios, may transfer
     uninvested cash balances into one or more joint trading accounts. The
     balances are invested in one or more repurchase agreements, which are fully
     collateralized by U.S. Treasury or U.S. government agency obligations with
     counterparties approved by the Board of Trustees, consistent with the
     Portfolio's investment policy.

     SECURITIES LENDING

     To generate additional income, each Portfolio may lend up to 33 1/3% of its
     assets pursuant to agreements requiring that the loan be continuously
     secured by any combination of cash, U.S. government or U.S. government
     agency securities, shares of an investment trust or mutual fund, or letters
     of credit as collateral equal at all times to at least 100% of the market
     value plus accrued interest on the securities lent. The cash collateral
     received by the Funds was pooled and at June 30, 2004, was invested in
     Repurchase Agreements (with interest rates ranging from 1.30% to 1.57% and
     maturity date of July 1, 2004), Commercial Paper (with interest rates of
     1.23% and maturity dates of March 11, 2005) and Master Notes (with interest
     rates ranging from 1.16% to 1.80% and maturity dates ranging from July 1,
     2004 to February 27, 2006). Information on the investment of cash
     collateral is shown in the Schedule of Portfolio Investments. The
     Portfolios receive payments from borrowers equivalent to the dividends and
     interest that would have been earned on securities lent while
     simultaneously seeking to earn income on the investment of cash collateral.
     Collateral is marked to market daily to provide a level of collateral at
     least equal to the market value of securities lent. There may be risks of
     delay in recovery of the securities or even loss of rights in the
     collateral should the borrower of the securities fail financially. However,
     loans will be made only to borrowers deemed by the Advisor to be of good
     standing and creditworthy under guidelines established by the Board of
     Trustees and when, in the judgement of the Advisor, the consideration which
     can be earned currently from such securities loans justifies the attendant
     risks. Loans are subject to termination by the Portfolios or the borrower
     at any time, and are, therefore, not considered to be illiquid investments.
     Bank One Trust Company N.A., an affiliate of the Advisor, serves as
     sub-custodian for the securities lending program.

     * Includes securities and cash collateral

     SECURITIES TRANSACTIONS AND RELATED INCOME

     Changes in holdings of portfolio securities shall be reflected no later
     than in the first calculation on the first business day following the trade
     date. Net realized gains or losses from sales of securities are determined
     on the specific identification cost method. Interest income and expenses
     are recognized on the accrual basis. Dividends are recorded on the
     ex-dividend date. Interest income includes premium amortization and
     discount accretion for both financial reporting and tax purposes.
     Amortization and accretion are calculated using the effective interest
     method.

     EXPENSES

     Direct expenses of a Portfolio are allocated to that Portfolio. The general
     expenses of the Trust are allocated among the respective Portfolios.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income, if any, are declared and paid
     annually for the Portfolios. Net realized capital gains, if any, are
     distributed at least annually.

     Distributions from net investment income and from net capital gains are
     determined in accordance with income tax regulations, which may differ from
     generally accepted accounting principles. These differences are primarily
     due to differing treatments for mortgage-backed securities, expiring
     capital loss carryforwards and deferrals of certain losses. Permanent book
     and tax basis differences have been reclassified among the components of
     net assets.

     FEDERAL INCOME TAX

     The Portfolios' policy is to continue to comply with the requirements of
     the Internal Revenue Code that are applicable to regulated investment
     companies and to distribute all its taxable income to its shareholders.
     Therefore, no federal income tax provision is required.

3. INVESTMENT ADVISORY AND ADMINISTRATION AGREEMENTS:

   The Trust and the Advisor are parties to an investment advisory agreement
   under which the Advisor is entitled to a fee, computed daily and paid
   monthly, of the following annual percentages of the average daily net assets
   of each Portfolio:

<Table>

                                                                    ADVISORY

    Large Cap Growth Portfolio..................................      0.65

    Diversified Equity Portfolio................................      0.74

    Equity Index Portfolio......................................      0.30

    Balanced Portfolio..........................................      0.70

    Bond Portfolio..............................................      0.60

    Government Bond Portfolio...................................      0.45
</Table>

   The Trust and One Group Administrative Services, Inc., (the "Administrator")
   are parties to an administration agreement under which the Administrator
   provides services for a fee that is computed daily and paid monthly, at an
   annual rate of 0.18% on the first $250 million in Trust average daily net
   assets (other than the assets in the Equity Index Portfolio) and 0.14% on
   Trust average daily net assets of $250 (other than the assets in the Equity
   Index Portfolio). The Administrator is entitled to a fee at the rate of 0.14%
   of the Equity Index Portfolio's average daily net assets.

   When the Portfolios invest in One Group Money Market Funds, the Advisor and
   the Administrator will waive a portion of its fees to eliminate duplication
   of fees. These waivers effectively reduce the advisory and administrative
   fees paid by the Portfolios, and are reflected in waivers on the Statements
   of Operations.

   Certain officers of the Trust are affiliated with the Advisor and the
   Administrator. Such officers receive no compensation from the Portfolios for
   serving in their respective roles.

   The Trust adopted a Trustee Deferred Compensation Plan (the "Plan") which
   allows the independent Trustees to defer the receipt of all or a portion of
   compensation related to performance of their duties as a Trustee. The
   deferred fees are invested in various One Group Mutual Funds until
   distribution in accordance with the Plan.

5. SUBSEQUENT EVENTS:

   On July 1, 2004, Bank One Corporation, the former corporate parent of the
   Advisor and Administrator, merged into JPMorgan Chase & Co. On that date the
   Advisor became an affiliate of J.P. Morgan Investment Management Inc.
   ("JPMIM"), the investment adviser to the JPMorgan Funds. The Advisor and
   JPMIM will continue as separate investment advisory entities, for the
   foreseeable future, and will continue to provide the same investment advisory
   services provided to the Trust and the JPMorgan Funds, respectively.

   On August 12, 2004, the Board of Trustees of the Trust approved an agreement
   with JPMorgan Chase Bank, an affiliate of the Advisor and the Administrator
   to act as the Funds' custodian. The transition of the custody
   responsibilities to JPMorgan Chase Bank is expected to be completed by
   December 2004 and is not anticipated to have a significant impact on the
   Funds' operations or their expenses.

   Additionally, on August 12, 2004, the Board of Trustees approved the
   appointment of JPMorgan Chase Bank as securities lending agent for the Trust
   that are permitted to lend their securities concurrent with the appointment
   of JPMorgan Chase Bank as custodian. Upon appointment of JPMorgan Chase Bank
   as securities lending agent, Bank One Trust Company, N.A. will no longer
   serve as sub-custodian.

INVESTMENT TRUST SEMI-ANNUAL REPORT

SHAREHOLDER EXPENSE EXAMPLE
HYPOTHETICAL $1,000 INVESTMENT AT BEGINNING OF PERIOD
JUNE 30, 2004
(UNAUDITED)

As a shareholder of the Portfolios, you incur two types of costs: (1)
transaction costs, including sales charges (loads) on purchase payments and
redemption fees; and (2) ongoing costs, including investment advisory fees,
administration fees and other Portfolio expenses. The examples below are
intended to help you understand your ongoing costs (in dollars) of investing in
the Portfolios and to compare these costs with the ongoing costs of investing in
other mutual funds. The examples assume that you had a $1,000 investment in the
Portfolio at the beginning of the reporting period, January 1, 2004, and
continued to hold your shares at the end of the reporting period, June 30, 2004.

In order to comply with newly issued regulatory requirements, the beginning
account value of this example will be $1,000. While this represents a change
from the action outlined in One Group Investment Trust's Commitment to Fund
Shareholders, this change will make it easier for shareholders to (1) estimate
their actual expenses, e.g. for shareholders holding less than $10,000 in a
fund, and (2) compare this information to similar information provided by other
mutual funds.

ACTUAL EXPENSES
For each Portfolio in the table below, the first line provides information about
actual account values and actual expenses. You may use the information in this
line, together with the amount you invested, to estimate the expenses that you
paid over the period. Simply divide your account value by $1,000 (for example,
an $8,600 account value divided by $1,000 = 8.6), then multiply the result by
the number in first line of each Portfolio under the heading entitled "Expenses
Paid During Period" to estimate the expenses you paid on your account during the
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line of each Portfolio in the table below provides information about
hypothetical account values and hypothetical expenses based on the Portfolio's
actual expense ratio and an assumed rate of return of 5% per year before
expenses, which is not the Portfolio'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 Portfolio and other funds. To do
so, compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) or redemption fees. Therefore, the second line for each
Portfolio in the table is useful in comparing ongoing costs only, and will not
help you determine the relative total costs of owning different funds. In
addition, if these transaction costs were included, your costs would have been
higher. The examples also assume all dividends and distributions have been
reinvested.

ITEM 2. CODE OF ETHICS.

     Disclose whether, as of the end of the period covered by the report, the
     registrant has adopted a 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. If the registrant has not adopted such a code of ethics,
     explain why it has not done so.

     NOT APPLICABLE - ONLY FOR ANNUAL REPORTS.

     The registrant must briefly describe the nature of any amendment, during
     the 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 file a copy of any such amendment as an
     exhibit pursuant to Item 11(a)(1), unless the registrant has elected to

     waiver, including an implicit waiver, from a provision of the 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

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



ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

      (a) (1) Disclose that the registrant's board of directors has
          determined that the registrant either:

               (i) Has at least one audit committee financial expert serving on
               its audit committee; or

               (ii) Does not have an audit committee financial expert serving on
               its audit committee.

          (2) If the registrant provides the disclosure required by paragraph
          (a)(1)(i) of this Item, it must disclose the name of the audit
          committee financial expert and whether that person is "independent."
          In order to be considered "independent" for purposes of this Item, a
          member of an audit committee may not, other than in his or her
          capacity as a member of the audit committee, the board of directors,
          or any other board committee:

               (i) Accept directly or indirectly any consulting, advisory, or
               other compensatory fee from the issuer; or

               (ii) Be an "interested person" of the investment company as
               defined in Section 2(a)(19) of the Act (15 U.S.C. 80a- 2(a)(19)).

          (3) If the registrant provides the disclosure required by paragraph
          (a)(1)(ii) of this Item, it must explain why it does not have an audit
          committee financial expert.


NOT APPLICABLE - ONLY FOR ANNUAL REPORTS.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

         (a) Disclose, under the caption Audit Fees, the aggregate fees billed
for each of the last two fiscal years for professional services rendered by the
principal accountant for the audit of the registrant's annual financial
statements or services that are normally provided by the accountant in
connection with statutory and regulatory filings or engagements for those fiscal
years.

         (b) Disclose, under the caption Audit-Related Fees, the aggregate fees
billed in each of the last two fiscal years for assurance and related services
by the principal accountant that are reasonably related to the performance of
the audit of the registrant's financial statements and are not reported under
paragraph (a) of this Item. Registrants shall describe the nature of the
services comprising the fees disclosed under this category.
         (c) Disclose, under the caption Tax Fees, the aggregate fees billed in
each of the last two fiscal years for professional services rendered by the
principal accountant for tax compliance, tax advice, and tax planning.
Registrants shall describe the nature of the services comprising the fees
disclosed under this category.

         (d) Disclose, under the caption All Other Fees, the aggregate fees
billed in each of the last two fiscal years for products and services provided
by the principal accountant, other than the services reported in paragraphs (a)
through (c) of this Item. Registrants shall describe the nature of the services
comprising the fees disclosed under this category.

         (e) (1) Disclose the audit committee's pre-approval policies and
procedures described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.



             (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.

         (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.

         (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.

         (h) Disclose whether the registrant's audit committee of the board of
directors has considered whether the provision of nonaudit 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.

NOT APPLICABLE - ONLY FOR ANNUAL REPORTS.

ITEM 5.   AUDIT COMMITTEE OF LISTED REGISTRANTS.
         (a)  If the registrant is a listed issuer as defined in Rule 10A-3

              registrant has a separately-designated standing audit committee

              Act (15 U.S.C. 78c(a)(58)(A)). If the registrant has such a
              committee, however designated, identify each committee member. If
              the entire board of directors is acting as the registrant's audit
              committee as specified in Section 3(a)(58)(B) of the Exchange Act
              (15 U.S.C. 78c(a)(58)(B)), so state.
         (b)  If applicable, provide the disclosure required by Rule 10A-3(d)
              under the Exchange Act (17CFR 240.10A-3(d)) regarding an exemption
              from the listing standards for all audit committees.
NOT APPLICABLE.
