                                                                       June 2005
- --------------------------------------------------------------------------------

                 As I write to you, inflation - a key driver of both the stock
                 and bond markets - appears to be under control. The U.S.
                 economy is in good health, and I expect the gross domestic
                 product (GDP) to grow between 3% and 3.5% in 2005. Meanwhile,
                 the Federal Reserve Board (the Fed) shows signs of nearing the
                 end of its interest-rate tightening schedule; it is likely to
                 leave the federal funds rate near 3.5% or 3.75%. Oil prices
                 have moved higher, rising above $50 a barrel and continuing to
                 constrain economic growth.

                 Although U.S. equity valuations are trading at historically
                 high levels for a rising interest-rate environment,
                 international valuations appear a little more reasonable.
                 Remarkably, long-term interest rates have remained low, which
                 has helped to support the stock market. Why? The bond market
                 seems to believe that the economy will slow. Absent inflation
                 and a rising dollar, longer-term interest rates actually
                 declined in 2005, increasing the value of longer-term bonds.
                 In my opinion, longer-term rates will continue to have a
                 significant impact on the direction of the stock and bond
                 markets over the next few quarters.

                 The growth in the U.S. budget deficit is of some concern.
                 Sooner or later, the government must cut spending and/or raise
                 taxes to pay its bills - both would be challenging for the
                 U.S. economy over the long term.


                                                                               3

 . . . C O N T I N U E D
========================--------------------------------------------------------

                 Consumers have their own budget deficits. Some pundits scoff
                 at the significance; others predict a day of reckoning. I
                 believe Americans have to curb their spending and start saving
                 more to support their eventual retirements. And while greater
                 savings may be a plus, a slowdown in consumer spending would
                 hurt economic growth.

                 Against this backdrop, investors may find that quality,
                 diversification, safety, liquidity, and patience are the
                 smartest strategies. For short-term investors, money markets
                 provide yields near 3%, with relative safety and liquidity.
                 Investors with longer-term horizons could see annual returns
                 of 4% to 5% a year in bonds, particularly if they reinvest the
                 interest. Stocks are likely to generate only modest gains
                 going forward; we see the equity markets providing
                 mid-single-digit returns over the next several years.

                 In the current investment environment, it would be prudent to
                 take what the market offers us and resist the urge to reach
                 for higher returns at dramatically greater risk. Sometimes
                 risk is simply risk and is not always rewarded with higher
                 returns. We will continue to look for value in our
                 investments, examine the risks, and not stray from our
                 investment discipline.

                 From everyone at USAA, thank you for your business and the
                 opportunity to serve your investment needs.

                   COMMENTARY on the Fund

HOW DID THE FUND PERFORM?

                 The USAA GNMA Trust had a total return of 5.32% for the year
                 ended May 31, 2005. This compares to a 5.19% return for the
                 Lipper GNMA Funds Average, 5.46% for the Lipper GNMA Funds
                 Index, and 6.47% for the Lehman Brothers GNMA 30-Year Index.

WHAT WAS THE MARKET ENVIRONMENT DURING THE PERIOD?

                 The dominating theme was the decline in long-term interest
                 rates despite the fact that the Federal Reserve Board (the Fed)
                 tripled the short-term federal funds rate, from 1% to 3%,
                 through 0.25% hikes at eight consecutive meetings of the
                 Federal Open Market Committee. As the period opened,
                 longer-term bond yields had already risen in anticipation of
                 the Fed's action, reaching the highest levels we had seen since
                 2002. The graph on the next page tracks the yield on U.S.
                 Treasury bonds of varying maturities as well as the target
                 federal funds rate over the past two years. In this
                 environment, longer-term bonds posted good absolute returns.

                 PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.

HOW DID MORTGAGE-BACKED SECURITIES PERFORM?

                 The period of rising short-term rates and falling long-term
                 rates proved to be a good environment for mortgage-backed
                 securities. Mortgage-backed secur ities have interest-rate
                 sensitivity closer to that of short-or intermediate-term
                 bonds, because even though mortgages may have 15-or 30-year
                 maturities, the bonds are paid off when a mortgage is
                 refinanced or a house is sold. Although homeowners were still
                 refinancing their mortgages during the period, the volume
                 declined somewhat, since many mortgages had already been
                 refinanced.

                 Mortgage-backed securities also performed well in relation to
                 corporate bonds. Corporate bonds were top performers in the
                 bond market in 2003 and 2004 as companies repaired their
                 balance sheets, but this turned around in March 2005 when
                 General Motors announced its biggest quarterly loss in
                 13 years,

                         COMMENTARY on the Fund

                 reminding investors that corporate bonds carry event risk. This
                 re-assessment of relative risk made mortgage-backed securities
                 a refuge, and for the first time in several years mortgage-

                 backed securities began outperforming corporate bonds of
                 similar interest-rate sensitivity. GNMAs in particular
                 benefited from the fact that, like U.S. Treasury bonds, they
                 are backed by the full faith and credit of the U.S.
                 government. Because your Fund must have at least 80% of
                 assets in GNMAs, it was not subject to the volatility that hit
                 the corporate bond market.

HOW DID YOU MANAGE THE FUND IN THIS ENVIRONMENT?

                 Given the low long-term interest-rate environment in the face
                 of Fed rate hikes, we felt it was prudent to keep the Fund's
                 interest-rate sensitivity relatively low. We also focused on
                 slightly higher coupon bonds that, while subject to prepayment
                 risk, tend to suffer less of a price decline if interest rates
                 rise. Our cautious stance hindered performance as rates stayed
                 low and even went down. However, we did take the opportunity to
                 deploy cash when rates spiked, such as at the end of the first
                 quarter of 2005.

SHOULD INVESTORS IN THE FUND BE CONCERNED ABOUT A POSSIBLE HOUSING "BUBBLE"?

                 No. While no one can say whether recent home price increases
                 are sustainable, your Fund is not invested in any of the new
                 types of mortgages (for example, interest-only mortgages) that
                 would be most at risk if housing prices were to fall.

WHAT'S YOUR MARKET OUTLOOK?

                 With economic growth moderating and global competition keeping
                 inflation in check despite higher energy and other commodity
                 prices, we believe the Fed may be nearing the end of its
                 tightening regime, especially as the federal funds rate nears
                 the 3.5% that existed before 9/11, when the Fed opened the
                 monetary flow to support the economy.

                 It pays to remember that bond investing is about earning
                 income. As the chart on page 10 shows, the bulk of your Fund's
                 total return has come from income as opposed to changes in the
                 Fund's price.

                 Thank you for the opportunity and privilege of serving you.

                         Public ACCOUNTING Firm

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF USAA GNMA TRUST:

We have audited the accompanying statement of assets and liabilities of the USAA
GNMA Trust (a portfolio of USAA Investment Trust) (the "Fund"), including the
portfolio of investments, as of May 31, 2005, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the three years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit. The financial highlights for each of
the periods presented through May 31, 2002, were audited by other auditors whose
report dated July 5, 2002, expressed an unqualified opinion on those statements
and financial highlights.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audit included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of May 31, 2005, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audit provides a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
USAA GNMA Trust at May 31, 2005, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for each of the three years in the
period then ended, in conformity with U.S. generally accepted accounting
principles.

                                                           /S/ ERNST & YOUNG LLP

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

         USAA INVESTMENT TRUST (the Trust), registered under the Investment
         Company Act of 1940 (the 1940 Act), as amended, is an open-end
         management investment company organized as a Massachusetts business
         trust consisting of 10 separate funds. The information presented in
         this annual report pertains only to the USAA GNMA Trust (the Fund),
         which is classified as diversified under the 1940 Act. The Fund's
         investment objective is to provide a high level of current income
         consistent with preservation of principal.

             A. SECURITY VALUATION - The value of each security is determined
                (as of the close of trading on the New York Stock Exchange on
                each business day the exchange is open) as set forth below:

                1. Debt securities are valued each business day by a pricing
                   service (the Service) approved by the Trust's Board of
                   Trustees. The Service uses the mean between quoted bid and
                   asked prices or the last sales price to price securities
                   when, in the Service's judgment, these prices are readily
                   available and are representative of the securities' market
                   values. For many securities, such prices are not readily
                   available. The Service generally prices these securities
                   based on methods that include consideration of yields or
                   prices of securities of comparable quality, coupon, maturity,
                   and type; indications as to values from dealers in
                   securities; and general market conditions.

                2. Securities purchased with original maturities of 60 days or
                   less are stated at amortized cost, which approximates market
                   value. Repurchase agreements are valued at cost.

                3. Securities for which market quotations are not readily
                   available or are considered unreliable, or whose values have
                   been materially affected by events occurring after the close
                   of their primary markets but before the pricing of the Fund,
                   are valued

USAA GNMA TRUST
MAY 31, 2005

                   in good faith at fair value, using methods determined by USAA
                   Investment Management Company (the Manager), an affiliate of
                   the Fund, under valuation procedures approved by the Trust's
                   Board of Trustees. Valuing these securities at fair value is
                   intended to cause the Fund's net asset value (NAV) to be more
                   reliable than it otherwise would be.

                   Fair value methods used by the Manager include, but are not
                   limited to, obtaining market quotations from secondary
                   pricing services, broker-dealers, or widely used quotation
                   systems. General factors considered in determining the fair
                   value of securities include fundamental analytical data, the
                   nature and duration of any restrictions on disposition of the
                   securities, and an evaluation of the forces that influenced
                   the market in which the securities are purchased and sold.

             B. FEDERAL TAXES - The Fund's policy is to comply with the
                requirements of the Internal Revenue Code applicable to
                regulated investment companies and to distribute substantially
                all of its income to its shareholders. Therefore, no federal
                income tax provision is required.

             C. INVESTMENTS IN SECURITIES - Security transactions are accounted
                for on the date the securities are purchased or sold (trade
                date). Gains or losses from sales of investment securities are
                computed on the identified cost basis. Interest income is
                recorded on the accrual basis. Discounts and premiums are
                amortized over the life of the respective securities, using the
                effective yield method for long-term securities and the
                straight-line method for short-term securities.

             D. REPURCHASE AGREEMENTS - The Fund may enter into repurchase
                agreements with commercial banks or recognized security dealers.
                These agreements are collateralized by obligations issued or
                guaranteed as to both principal and interest by the


                                                                              25

                U.S. government, its agencies, or its instrumentalities.
                Government-sponsored enterprises (GSEs), such as Federal
                National Mortgage Association (Fannie Mae) and Federal Home Loan
                Mortgage Corporation (Freddie Mac), are supported only by the
                credit of the issuing U.S. government agency, and are neither
                issued nor guaranteed by the U.S. government. Obligations
                pledged as collateral are required to maintain a value equal to
                or in excess of the repurchase agreement price plus accrued
                interest and are held by the Fund, either through its regular
                custodian or through a special "tri-party" custodian that
                maintains separate accounts for both the Fund and its
                counterparty, until maturity of the repurchase agreement. The
                Fund's Manager monitors the creditworthiness of sellers with
                which the Fund may enter into repurchase agreements.

             E. SECURITIES PURCHASED ON A WHEN-ISSUED BASIS - Delivery and
                payment for securities that have been purchased by the Fund on a
                when-issued basis can take place a month or more after the trade
                date. During the period prior to settlement, these securities do
                not earn interest, are subject to market fluctuation, and may
                increase or decrease in value prior to their delivery. The Fund
                maintains segregated assets with a market value equal to or
                greater than the amount of its purchase commitments. The
                purchase of securities on a when-issued basis may increase the
                volatility of the Fund's NAV to the extent that the Fund makes
                such purchases while remaining substantially fully invested. The
                Fund had no when-issued commitments as of May 31, 2005.

             F. EXPENSES PAID INDIRECTLY - Through arrangements with the Fund's
                custodian and other banks utilized by the Fund for cash
                management purposes, realized credits, if any, generated from
                cash balances in the Fund's bank accounts are used to

                reduce the Fund's expenses. For the year ended May 31, 2005,
                these custodian and other bank credits reduced the Fund's
                expenses by $3,000.

             G. INDEMNIFICATIONS - 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 that contain a variety of
                representations and warranties that provide 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 that have not yet occurred.
                However, the Trust expects the risk of loss to be remote.

             H. USE OF ESTIMATES - The preparation of financial statements in
                conformity with U.S. generally accepted accounting principles
                requires management to make estimates and assumptions that may
                affect the reported amounts in the financial statements.

(2) LINES OF CREDIT
- --------------------------------------------------------------------------------

         Effective January 6, 2005, the Fund participates in a joint,
         short-term, revolving, committed loan agreement of $300 million with
         USAA Capital Corporation (CAPCO), an affiliate of the Manager. The
         purpose of the agreement is to meet temporary or emergency cash needs,
         including redemption requests that might otherwise require the untimely
         disposition of securities. Subject to availability under the agreement,
         the Fund may borrow from CAPCO an amount up to 5% of the Fund's total
         assets at a rate per annum equal to the rate at which CAPCO obtains
         funding in the capital markets, with no markup.

         The USAA funds that are party to the loan agreement are assessed
         facility fees by CAPCO based on the funds' assessed proportionate


                                                                              27

 N O T E S

           (continued)

USAA GNMA TRUST
MAY 31, 2005

         share of CAPCO's operating expenses related to obtaining and
         maintaining CAPCO's funding programs in total (in no event to exceed
         0.09% annually of the $300 million loan agreement). The facility fees
         are allocated among the funds based on their respective average net
         assets for the period.

         Prior to January 6, 2005, the loan agreement with CAPCO was in the
         amount of $400 million, and the Fund also participated with other USAA
         funds in a joint, short-term, revolving, committed loan agreement of
         $100 million with Bank of America and State Street Bank and Trust
         Company (State Street), under which Bank of America and State Street
         both committed $50 million. Subject to availability under its agreement
         with Bank of America and State Street, the Fund could borrow from Bank
         of America and State Street, at the federal funds rate plus a 0.50%
         markup, an amount which, when added to outstanding borrowings under the
         CAPCO agreement, did not exceed 25% of the Fund's total assets. The
         USAA funds that were party to the loan agreement with Bank of America
         and State Street were assessed facility fees in an annual amount equal
         to 0.09% of the $100 million loan agreement, whether used or not. The
         facility fees were allocated among the funds based on their respective
         average net assets for the period.

         For the year ended May 31, 2005, the Fund paid CAPCO facility fees of
         $4,000, which represents 2.1% of total fees paid to CAPCO by the USAA
         funds. The Fund had no borrowings under any of these agreements during
         the year ended May 31, 2005.

(3) DISTRIBUTIONS
- --------------------------------------------------------------------------------

         The character of any distributions made during the year from net
         investment income or net realized gains is determined in accordance
         with federal tax regulations and may differ from those determined in
         accordance with U.S. generally accepted accounting principles. Also,
         due to the timing of distributions, the fiscal year in which amounts
         are

 N O T E S

           to FINANCIAL Statements
           (continued)

USAA GNMA TRUST
MAY 31, 2005

         distributed may differ from the year that the income or realized gains
         were recorded by the Fund.

         During the current fiscal year, permanent differences between book-
         basis and tax-basis accounting for security paydowns, and the
         expiration of capital loss carryovers resulted in reclassifications
         made to the statement of assets and liabilities to decrease paid-in
         capital by $3,499,000, increase accumulated undistributed net
         investment income by $4,390,000, and increase accumulated net realized
         loss on investments by $891,000. This reclassification has no effect on
         net assets.

         The tax character of distributions paid during the years ended May 31,
         2005, and 2004, was as follows:

         
         
                                                     2005                2004
                                                 -------------------------------
                                                               
         Ordinary income*                        $28,942,000         $32,030,000
         

         *Includes distribution of short-term realized capital gains, if any,
          which are taxable as ordinary income.

         As of May 31, 2005, the components of net assets representing
         distributable earnings on a tax basis were as follows:

         
                                                                 
         Undistributed ordinary income                              $    474,000
         Accumulated capital and other losses                        (39,462,000)
         Unrealized appreciation                                       6,171,000
         

         Net investment income is accrued daily as dividends and distributed to
         shareholders monthly. Distributions of realized gains from security
         transactions not offset by capital losses are made annually in the
         succeeding fiscal year or as otherwise required to avoid the payment of
         federal taxes. For the year ended May 31, 2005, the Fund had expired
         capital loss carryovers of $3,499,000. At May 31, 2005, the Fund had a
         current post-October deferred capital loss of $2,129,000 and capital
         loss carryovers of $37,333,000, for federal income tax purposes. The
         post-October loss will be recognized on the first day of the following
         fiscal year. If not offset by subsequent capital gains, the capital
         loss carryovers will expire between 2008 and 2013, as shown on the next
         page. It is


                                                                              29

         $211,506,000 and $224,839,000, respectively.

         As of May 31, 2005, the cost of securities, including short-term
         securities, for federal income tax purposes, was $586,043,000.

         Gross unrealized appreciation and depreciation of investments as of May
         31, 2005, for federal income tax purposes, were $7,219,000 and
         $1,048,000, respectively, resulting in net unrealized appreciation of
         $6,171,000.

(5) LENDING OF PORTFOLIO SECURITIES
- --------------------------------------------------------------------------------

         The Fund, through its third-party securities-lending agent,
         Metropolitan West Securities LLC (MetWest), may lend its securities to
         qualified financial institutions, such as certain broker-dealers, to
         earn additional income. The borrowers are required to secure their
         loans continuously with cash collateral in an amount at least equal to
         the fair value of the

           (continued)

USAA GNMA TRUST
MAY 31, 2005

         securities loaned, initially in an amount at least equal to 102% of the
         fair value of domestic securities loaned and 105% of the fair value of
         international securities loaned. Cash collateral is invested in
         high-quality short-term investments. The Fund and MetWest retain 80%
         and 20%, respectively, of the income earned from the investment of cash
         received as collateral. MetWest receives no other fees from the Fund
         for its services as securities-lending agent. Risks to the Fund in
         securities-lending transactions are that the borrower may not provide
         additional collateral when required or return the securities when due,
         and that the value of the short-term investments will be less than the
         amount of cash collateral required to be returned to the borrower. The
         Fund had no securities-lending transactions during the year ended May
         31, 2005.

(6) TRANSACTIONS WITH MANAGER
- --------------------------------------------------------------------------------

             A. MANAGEMENT FEES - The Manager carries out the Fund's investment
                policies and manages the Fund's portfolio. The investment
                management fee for the Fund is composed of a base fee and a
                performance adjustment that increases or decreases the base fee
                depending upon the performance of the Fund relative to the
                performance of the Lipper GNMA Funds Index, which tracks the
                total return performance of the 10 largest funds in the Lipper
                GNMA Funds category. The Fund's base fee is accrued daily and
                paid monthly at an annualized rate of 0.125% of its average net
                assets.

                The performance adjustment is calculated monthly by comparing
                the Fund's performance to that of the Lipper index over the
                performance period. The performance period for the Fund consists
                of the current month plus the previous 35 months.

                The annual performance adjustment rate is multiplied by the
                average net assets of the Fund over the entire performance
                period, which is then multiplied by a fraction, the numerator of


                                                                              31

                which is the number of days in the month and the denominator of
                which is 365 (366 in leap years). The resulting amount is then
                added to (in the case of overperformance) or subtracted from (in
                the case of underperformance) the base fee, as referenced in the
                following chart:



OVER/UNDER PERFORMANCE                   ANNUAL ADJUSTMENT RATE

+/- 0.51% to 1.00%                       +/- 0.05%

+/- 1.01% and greater                    +/- 0.06%


(1)Based on the difference between average annual performance of the Fund and
   its relevant index, rounded to the nearest 0.01%.

                Under the performance fee arrangement, the Fund will pay a
                positive performance fee adjustment for a performance period
                whenever the Fund outperforms the Lipper GNMA Funds Index over
                that period, even if the Fund had overall negative returns
                during the performance period.

                For the year ended May 31, 2005, the Fund incurred total
                management fees, paid or payable to the Manager, of $800,000,
                which included a performance adjustment of $45,000 that
                increased the base management fee of 0.125% by 0.007%.

             B. ADMINISTRATION AND SERVICING FEES - The Manager provides certain
                administration and shareholder servicing functions for the Fund.
                For such services, the Manager receives a fee accrued daily and
                paid monthly at an annualized rate of 0.15% of the Fund's
                average net assets. For the year ended May 31, 2005, the Fund
                incurred administration and servicing fees, paid or payable to
                the Manager, of $907,000.

             C. TRANSFER AGENT'S FEES - USAA Transfer Agency Company, d/b/a USAA

                Manager, provides transfer agent services to the Fund based on
                an annual charge of $25.50 per shareholder account plus out-of-
                pocket expenses. The Fund also pays SAS fees that are related to
                the administration and servicing of accounts that are traded on
                an omnibus basis. For the year ended May 31, 2005, the Fund
                incurred transfer agent's fees, paid or payable to SAS, of
                $848,000.

             D. UNDERWRITING SERVICES - The Manager provides exclusive
                underwriting and distribution of the Fund's shares on a
                continuing best-efforts basis. The Manager receives no
                commissions or fees for this service.

(7) TRANSACTIONS WITH AFFILIATES
- --------------------------------------------------------------------------------

                Certain trustees and officers of the Fund are also directors,
                officers, and/or employees of the Manager. None of the
                affiliated trustees or Fund officers received any compensation
                from the Fund.


                                                                              33

MAY 31, 2005

EXAMPLE
- --------------------------------------------------------------------------------

         As a shareholder of the Fund, you incur two types of costs: direct
         costs, such as wire fees, redemption fees, and low balance fees; and
         indirect costs, including management fees, transfer agency fees, and
         other Fund operating expenses. This example is intended to help you
         understand your indirect costs, also referred to as "ongoing costs,"
         (in dollars) of investing in the Fund and to compare these costs with
         the ongoing costs of investing in other mutual funds.

         The example is based on an investment of $1,000 invested at the
         beginning of the period and held for the entire six-month period of
         December 1, 2004, through May 31, 2005.

ACTUAL EXPENSES
- --------------------------------------------------------------------------------

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
- --------------------------------------------------------------------------------

         The second line of the table 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


                                                                              35

         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 other funds.

         Please note that the expenses shown in the table are meant to highlight
         your ongoing costs only and do not reflect any direct costs, such as
         wire fees, redemption fees, or low balance fees. Therefore, the second
         line of the table is useful in comparing ongoing costs only, and will
         not help you determine the relative total costs of owning different
         funds. In addition, if these direct costs were included, your costs
         would have been higher.

USAA GNMA TRUST
MAY 31, 2005

         At a meeting of the Board of Trustees held on April 27-28, 2005, the
         Board, including the Trustees who are not "interested persons" of the
         Trust (the "Independent Trustees"), approved the continuance of the
         Investment Advisory Agreement between the Trust and the Manager with
         respect to the Fund.

         In advance of the meeting, the Trustees received and considered a
         variety of information relating to the Investment Advisory Agreement
         and the Manager, and were given the opportunity to ask questions and
         request additional information from management. The information
         provided to the Board included, among other things: (i) a separate
         report prepared by an independent third party, which provided a
         statistical analysis comparing the Fund's investment performance,
         expenses, and fees to comparable investment companies; (ii) information
         concerning the services rendered to the Fund, as well as information
         regarding the Manager's revenues and costs of providing services to the
         Fund and compensation paid to affiliates of the Manager; and (iii)
         information about the Manager's operations and personnel. Prior to
         voting, the Independent Trustees reviewed the proposed continuance of
         the Investment Advisory Agreement with management and with experienced
         independent counsel and received materials from such counsel discussing
         the legal standards for their consideration of the proposed
         continuation of the Investment Advisory Agreement with respect to the
         Fund. The Independent Trustees also reviewed the proposed continuation
         of the Investment Advisory Agreement with respect to the Fund in
         private sessions with their counsel at which no representatives of
         management were present.

         At each regularly scheduled meeting of the Board and its committees,
         the Board of Trustees of the Trust receives and reviews, among other
         things, information concerning the Fund's performance and related
         services provided by the Manager. At the meeting at which the renewal
         of the Investment Advisory Agreement is considered, particular focus is
         given to information concerning Fund performance, comparability

         the Investment Advisory Agreement included certain types of information
         previously received at such meetings.

         After full consideration of a variety of factors, the Board of
         Trustees, including the Independent Trustees, voted to approve the
         Investment Advisory Agreement. In approving the Investment Advisory
         Agreement, the Trustees did not identify any single factor as
         controlling, and each Trustee attributed different weights to various
         factors. Throughout their deliberations, the Independent Trustees were
         represented and assisted by independent counsel.

         NATURE, EXTENT, AND QUALITY OF SERVICES. In considering the nature,
         extent, and quality of the services provided by the Manager under the
         Investment Advisory Agreement, the Board of Trustees reviewed
         information provided by the Manager relating to its operations and
         personnel. The Board also took into account its familiarity with the
         Manager's management through Board meetings, discussions, and reports
         during the preceding year. The Board considered the fees paid to the
         Manager and the services provided to the Fund by the Manager under the
         Investment Advisory Agreement, as well as other services provided by
         the Manager and its affiliates under other agreements, and the
         personnel who provide these services. In addition to the investment
         advisory services provided to the Fund, the Manager and its affiliates
         provide administrative services, stockholder services, oversight of
         Fund accounting, marketing services, assistance in meeting legal and
         regulatory requirements, and other services necessary for the operation
         of the Fund and the Trust.

         The Board considered the Manager's management style and the performance
         of its duties under the Investment Advisory Agreement. The Board
         considered the level and depth of knowledge of the Manager, including
         the professional experience and qualifications of

         its senior and investment personnel, as well as current staffing
         levels. The allocation of the Fund's brokerage, including the Manager's
         process for monitoring "best execution," was also considered. The
         Manager's role in coordinating the activities of the Fund's other
         service providers was also considered. The Board considered the
         Manager's financial condition and that it had the financial wherewithal
         to continue to provide the same scope and high quality of services
         under the Investment Advisory Agreement. In reviewing the Investment
         Advisory Agreement, the Board focused on the experience, resources, and
         strengths of the Manager and its affiliates in managing investment
         companies, including the Fund.

         The Board also reviewed the compliance and administrative services
         provided to the Fund by the Manager, including oversight of the Fund's
         day-to-day operations and oversight of Fund accounting. The Manager and
         its affiliates provide compliance and administrative services to the
         Fund. The Trustees, guided also by information obtained from their
         experiences as directors/trustees of the Fund and other investment
         companies managed by the Manager, also focused on the quality of the
         Manager's compliance and administrative staff.

         EXPENSES AND PERFORMANCE. In connection with its consideration of the
         Investment Advisory Agreement, the Board evaluated the Fund's advisory
         fees and total expense ratio as compared to other open-end investment
         companies deemed to be comparable to the Fund as determined by the
         independent third party in its report. The Fund's expenses were
         compared to (i) a group of investment companies chosen by the
         independent third party to be comparable to the Fund based upon certain
         factors, including fund type, comparability of investment objectives
         and classifications, sales load type (in this case, investment
         companies with no sales loads), asset size, and expense components (the
         "expense group") and (ii) a larger group of investment companies that
         includes all no-load retail open-end investment companies in similar
         investment classifications/objectives


                                                                              39

         as the Fund regardless of asset size, excluding outliers (the "expense
         universe"). Among other data, the Board noted that the Fund's
         management fee rate -- which includes advisory and administrative
         services and the effects of any performance adjustment -- was the
         lowest in its expense group and below the median of its expense
         universe. The data indicated that the Fund's total expenses were the
         lowest in its expense group and below the median of its expense
         universe. The Board took into account the various services provided to
         the Fund by the Manager and its affiliates. The Board also noted the
         level and method of computing the management fee, including the
         performance adjustment to such fee.

         In considering the Fund's performance, the Board of Trustees noted that
         the Board reviews at its regularly scheduled meetings information about
         the Fund's performance results. The Trustees also reviewed various
         comparative data provided to them in connection with their
         consideration of the renewal of the Investment Advisory Agreement,
         including, among other information, a comparison of the Fund's average
         annual total return with its Lipper index and with that of other mutual
         funds deemed to be in its peer group by the independent third party in
         its report (the "performance universe"). The Fund's performance
         universe consisted of the Fund and all retail and institutional
         open-end investment companies with the same classification/objective as
         the Fund regardless of asset size or primary channel of distribution.
         This comparison indicated that the Fund's performance exceeded the
         average of its performance universe and its Lipper index for the one-,
         three-, and five-year periods ended December 31, 2004. The Board also
         noted that the Fund's percentile performance ranking was in the top 50%
         of its performance universe for the one-and three-year periods ended
         December 31, 2004.

         COMPENSATION AND PROFITABILITY. The Board took into consideration the
         level and method of computing the management fee. The information
         considered by the Board included operating profit margin information

         for the Manager's business as a whole. The Board also received and
         considered profitability information related to the management revenues
         from the Fund. This consideration included a broad review of the
         methodology used in the allocation of certain costs to the Fund. The
         Trustees reviewed the profitability of the Manager's relationship with
         the Fund before tax expenses. In reviewing the overall profitability of
         the management fee to the Manager, the Board also considered the fact
         that affiliates provide shareholder servicing and administrative
         services to the Fund for which they receive compensation. The Board
         also considered the possible direct and indirect benefits to the
         Manager from its relationship with the Trust, including that the
         Manager may derive reputational and other benefits from its association
         with the Fund. The Trustees recognized that the Manager should be
         entitled to earn a reasonable level of profits in exchange for the
         level of services it provides to the Fund and the entrepreneurial risk
         that it assumes as Manager. The Trustees also noted the relatively low
         management fee and total expenses of the Fund as compared to its peer
         group and peer universe.

         ECONOMIES OF SCALE. The Board considered whether there should be
         changes in the management fee rate or structure in order to enable the
         Fund to participate in any economies of scale that the Manager may
         experience as a result of growth in the Fund's assets. The Board noted
         that the Fund's contractual management fee is below the asset-weighted
         average of funds at all asset levels in its peer group as set forth in
         the report prepared by the independent third party. The Board also took
         into account management's discussion of the relatively small universe
         of funds that currently have breakpoints in their advisory fee. The
         Board determined that the current investment management fee structure
         was reasonable.

         CONCLUSIONS. The Board reached the following conclusions regarding the
         Fund's Investment Advisory Agreement with the Manager, among others:
         (i) the Manager has demonstrated that it possesses the capability


                                                                              41

         and resources to perform the duties required of it under the Investment
         Advisory Agreement; (ii) the Manager maintains an appropriate
         compliance program; (iii) the performance of the Fund is reasonable in
         relation to the performance of funds with similar investment objectives
         and to relevant indices; (iv) the Fund's advisory expenses are
         reasonable in relation to those of similar funds and to the services to
         be provided by the Manager; and (v) the Manager's level of
         profitability from its relationship with the Fund is reasonable. Based
         on its conclusions, the Board determined that continuation of the
         Investment Advisory Agreement would be in the interests of the Fund and
         its shareholders.

ITEM 2.  CODE OF ETHICS.

On June 25, 2003, the Board of Trustees of USAA Investment Trust approved a Code
of Ethics  (Sarbanes Code) applicable  solely to its senior financial  officers,
including  its principal  executive  officer  (President),  as defined under the
Sarbanes-Oxley  Act of 2002 and  implementing  regulations of the Securities and
Exchange  Commission.  A copy of the Sarbanes  Code is attached as an Exhibit to

No amendments  have been made to the Sarbanes Code since it was adopted,  and no
waivers  (explicit or implicit)  from a provision of the Sarbanes Code have been
granted.

Chair  Professor  of  Finance  since  1996.  Dr.  Starks  also has  served  as a
consultant  to  numerous  clients,  including  accounting  firms,  on a range of
finance,  accounting and auditing issues. Dr. Starks is an independent  director
who serves as a member of the Audit Committee,  Pricing and Investment Committee
and  the  Corporate  Governance  Committee  of the  Board  of  Trustees  of USAA
Investment Trust.



ITEM 4.  PRINCIPAL ACCOUNTANT FEES AND SERVICES.

All services were preapproved by the Audit Committee.

years ended May 31, 2005 or 2004.

(e)(1) AUDIT COMMITTEE  PRE-APPROVAL POLICY. All audit and non-audit services to
be performed for the Registrant by Ernst & Young LLP must be pre-approved by the
Audit Committee. The Audit Committee Charter also permits the Chair of the Audit
Committee  to  pre-approve  any  permissible  non-audit  service  that  must  be
commenced  prior to a scheduled  meeting of the Audit  Committee.  All non-audit
services were pre-approved by the Audit Committee or its Chair,  consistent with
the Audit Committee's preapproval procedures.

   (2)  Not applicable.

(f)  Not applicable.

rendered to the Registrant and the Registrant's  investment  adviser,  IMCO, and
the Funds'  transfer  agent, SAS, for May 31,  2005 and 2004 were  $109,143  and
$92,814, respectively.

(h) Ernst & Young LLP provided  non-audit services to IMCO in 2005 and 2004 that
were not required to be pre-approved by the Registrant's Audit Committee because
the services were not directly  related to the  operations  of the  Registrant's
funds.  The  Board  of  Directors/Trustees  will  consider  Ernst & Young  LLP's
independence and will consider whether the provision of these non-audit services
to IMCO is compatible with maintaining Ernst & Young LLP's independence.

procedure for shareholders to recommend candidates to serve on the Board.



ITEM 10.  CONTROLS AND PROCEDURES

The  principal  executive  officer  and  principal  financial  officer  of  USAA
Investment Trust (Trust) have concluded that the Trust's disclosure controls and
procedures are sufficient to ensure that information required to be disclosed by
the Trust in this Form N-CSR was recorded,  processed,  summarized  and reported
within the time periods  specified in the Securities  and Exchange  Commission's
rules and forms,  based upon such  officers'  evaluation  of these  controls and
procedures as of a date within 90 days of the filing date of the report.

There  were  no  significant  changes  or  corrective  actions  with  regard  to
significant deficiencies or material weaknesses in the Trust's internal controls
or in other  factors  that  could  significantly  affect  the  Trust's  internal
controls  subsequent to the date of their  evaluation.  Disclosure  controls and
procedures  were  established  for the new  section of the  shareholder  reports
detailing  the factors  considered  by the Funds' Board in approving  the Funds'
advisory agreements.



ITEM 11.  EXHIBITS.

(a)(1). Code of Ethics pursuant to Item 2 of Form N-CSR is filed hereto exactly
        as set forth below:


                                 CODE OF ETHICS
                         FOR PRINCIPAL EXECUTIVE OFFICER
                          AND SENIOR FINANCIAL OFFICERS

                             USAA MUTUAL FUND, INC.
                           USAA TAX-EXEMPT FUND, INC.
                              USAA INVESTMENT TRUST
                            USAA STATE TAX-FREE TRUST
                           USAA LIFE INVESTMENT TRUST

I.       PURPOSE OF THE CODE OF ETHICS

         USAA Mutual Fund,  Inc.,  USAA Tax-Exempt  Fund,  Inc., USAA Investment
Trust,  USAA State Tax-Free Trust and USAA Life Investment Trust  (collectively,
the Funds,  and each a Company)  have  adopted this code of ethics (the Code) to
comply  with  Section  406 of the  Sarbanes-Oxley  Act of  2002  (the  Act)  and
implementing  regulations of the Securities and Exchange  Commission  (SEC). The
Code applies to each Company's Principal Executive Officer,  Principal Financial
Officer and Principal  Accounting Officer (each a Covered Officer),  as detailed
in Appendix A.

   The purpose of the Code is to promote:
   o     honest and ethical conduct, including the ethical handling of actual or
         apparent conflicts of interest between the Covered Officers' personal
         and professional relationships;
   o     full, fair, accurate, timely and understandable disclosure in reports
         and documents that each Company files with, or submits to, the SEC and
         in other public communications made by each Company;
   o     compliance with applicable laws and governmental rules and regulations;
   o     prompt internal reporting of violations of the Code to the Chief Legal
         Officer of each Company, the President of each Company (if the
         violation concerns the Treasurer) and the Chairman of the Board of
         Directors/Trustees of each Company; and
   o     accountability for adherence to the Code.

         Each  Covered  Officer  should  adhere to a high  standard  of business
ethics and should be sensitive to actual and apparent conflicts of interest.

II.      CONFLICTS OF INTEREST

A.       DEFINITION OF A CONFLICT OF INTEREST.

         A conflict of interest exists when a Covered Officer's private interest
influences,  or reasonably appears to influence,  the Covered Officer's judgment
or ability to act in the best interests of the Funds and their shareholders. For
example,  a  conflict  of  interest  could  arise if a  Covered  Officer,  or an
immediate family member,  receives  personal  benefits as a result of his or her
position with the Funds.

         Certain  conflicts  of  interest  arise  out of  relationships  between
Covered  Officers and the Funds and are already  subject to conflict of interest
provisions  in the  Investment  Company  Act of  1940  (the  1940  Act)  and the
Investment  Advisers  Act of 1940  (the  Advisers  Act).  For  example,  Covered
Officers  may not  individually  engage in certain  transactions  with the Funds
because of their status as  "affiliated  persons" of the Funds.  The USAA Funds'
and  USAA  Investment   Management  Company's  (IMCO)  compliance  programs  and
procedures are designed to prevent, or identify and correct, violations of these
provisions.  This Code does not, and is not intended to, repeat or replace these
programs and  procedures,  and such  conflicts fall outside of the parameters of
this Code.

         Although  typically not presenting an opportunity for improper personal
benefit,  conflicts  could  arise  from,  or as a  result  of,  the  contractual
relationships  between the Funds and IMCO of which the Covered Officers are also
officers  or  employees.  As a result,  this Code  recognizes  that the  Covered
Officers  will, in the normal course of their duties  (whether  formally for the
Funds or for IMCO,  or for both),  be  involved  in  establishing  policies  and
implementing  decisions that will have different  effects on IMCO and the Funds.
The  participation  of Covered  Officers in such  activities  is inherent in the
contractual  relationship  between the Funds and IMCO and is consistent with the
performance  by the Covered  Officers of their  duties as officers of the Funds.
Thus,  if performed in  compliance  with the  provisions of the 1940 Act and the
Advisers Act, such activities will be deemed to have been handled ethically.  In
addition, it is recognized by each Company's Board of Directors/Trustees (each a
Board,  and  collectively  the  Boards)  that the Covered  Officers  also may be
officers or employees of one or more other investment  companies covered by this
joint USAA Funds' Code.

         B.       GENERAL RULE.  Covered Officers Should Avoid Actual and
                  Apparent Conflicts of Interest.

         Conflicts of interest,  other than the  conflicts  described in the two
preceding  paragraphs,  are covered by the Code.  The  following  list  provides
examples of conflicts of interest  under the Code, but Covered  Officers  should
keep in mind that these examples are not exhaustive.  The overarching  principle
is that  the  personal  interest  of a  Covered  Officer  should  not be  placed
improperly before the interest of the Funds and their shareholders.

         Each Covered  Officer must not engage in conduct  that  constitutes  an
actual conflict of interest between the Covered Officer's  personal interest and
the interests of the Funds and their shareholders.  Examples of actual conflicts
of interest are listed below but are not  exclusive.  Each Covered  Officer must
not:

   o     use his personal influence or personal relationships improperly to
         influence investment decisions or financial reporting by the Funds
         whereby the Covered Officer would benefit personally to the detriment
         of the Funds and their shareholders;
   o     cause the Funds to take action, or fail to take action, for the
         individual personal benefit of the Covered Officer rather than the
         benefit of the Funds and their shareholders.
   o     accept gifts, gratuities, entertainment or any other benefit from any
         person or entity that does business or is seeking to do business with
         the Funds during contract negotiations.
   o     accept gifts, gratuities, entertainment or any other benefit with a
         market value over $100 per person, per year, from or on behalf of any
         person or entity that does, or seeks to do, business with or on behalf
         of the Funds.
             o   EXCEPTION.  Business-related entertainment such as meals, and
                 tickets to sporting or theatrical events, which are infrequent
                 and not lavish are excepted from this prohibition.  Such
                 entertainment must be appropriate as to time and place,
                 reasonable and customary in nature, modest in cost and value,
                 incidental to the business, and not so frequent as to raise any
                 question of impropriety (Customary Business Entertainment).

         Certain  situations  that could present the appearance of a conflict of
interest  should  be  discussed  with,  and  approved  by,  or  reported  to, an
appropriate person. Examples of these include:

   o     service  as a  director  on the board or an  officer  of any  public or
         private  company,  other  than a USAA  company  or a  Company,  must be
         approved  by the USAA Funds' and IMCO's  Code of Ethics  Committee  and
         reported to each affected Company.
   o     the receipt of any non-nominal  (i.e.,  valued over $25) gifts from any
         person or  entity  with  which a Company  has  current  or  prospective
         business  dealings  must be reported to the Chief  Legal  Officer.  For
         purposes of this Code, the individual holding the title of Secretary of
         a Company shall be considered the Chief Legal Officer of a Company.
   o     the receipt of any  business-related  entertainment  from any person or
         entity  with  which the Funds  have  current  or  prospective  business
         dealings must be approved in advance by the Chief Legal Officer  unless
         such entertainment qualifies as Customary Business Entertainment.
   o     any ownership interest in, or any consulting or employment relationship
         with, any of the Company's  service  providers,  other than IMCO or any
         other USAA  company,  must be approved by the  Chairman of the Board of
         the Directors/Trustees and reported to each affected Board.
   o     any  material  direct or indirect  financial  interest in  commissions,
         transaction  charges  or  spreads  paid  by  the  Funds  for  effecting
         portfolio transactions or for selling or redeeming shares other than an
         interest  arising  from  the  Covered  Officer's  employment,  such  as
         compensation or equity  ownership should be approved by the Chairman of
         the Board of Directors/Trustees and reported to each affected Board.

III.     DISCLOSURE AND COMPLIANCE REQUIREMENTS

   o     Each Covered  Officer  should  familiarize  himself with the disclosure
         requirements  applicable to the Funds,  and the procedures and policies
         implemented to promote full, fair, accurate,  timely and understandable
         disclosure by each Company.

   o     Each Covered Officer should not knowingly misrepresent, or cause others
         to  misrepresent,  facts about the Funds to others,  whether  within or
         outside  the  Funds,  including  to the Funds'  Directors/Trustees  and
         auditors,    and   to   government   regulators   and   self-regulatory
         organizations.

   o     Each Covered Officer should, to the extent  appropriate within his area
         of  responsibility,  consult with other  officers and  employees of the
         Funds and IMCO with the goal of promoting full, fair, accurate,  timely
         and  understandable  disclosure in the reports and documents filed by a
         Company   with,   or  submitted  to,  the  SEC,  and  in  other  public
         communications made by the Funds.

   o     Each Covered Officer is responsible  for promoting  compliance with the
         standards  and  restrictions  imposed  by  applicable  laws,  rules and
         regulations,  and promoting  compliance with the USAA Funds' and IMCO's
         operating policies and procedures.

   o     A Covered Officer should not retaliate against any person who reports a
         potential violation of this Code in good faith.

   o     A Covered Officer should notify the Chief Legal Officer  promptly if he
         knows of any  violation  of the  Code.  Failure  to do so  itself  is a
         violation of this Code.

IV.      REPORTING AND ACCOUNTABILITY

         A.    INTERPRETATION  OF THE CODE.  The  Chief  Legal  Officer  of each
               Company  is  responsible  for  applying  this  Code  to  specific
               situations in which  questions are presented under it and has the
               authority to interpret the Code in any particular situation.  The
               Chief Legal Officer  should  consult,  if  appropriate,  the USAA
               Funds'   outside   counsel   or  counsel   for  the   Independent
               Directors/Trustees. However, any approvals or waivers sought by a
               Covered Officer will be reported initially to the Chairman of the
               Board of  Directors/Trustees  and will be considered by the Board
               of Directors/Trustees.

         B.    REQUIRED REPORTS

         o     EACH COVERED OFFICER MUST:
               o    Upon  adoption of the Code,  affirm in writing to the Boards
                    that he has received, read and understands the Code.
               o    Annually  thereafter  affirm to the Chief Legal Officer that
                    he has complied with the requirements of the Code.

         o     THE CHIEF LEGAL OFFICER MUST:
               o    report to the Board about any matter or situation  submitted
                    by a Covered Officer for interpretation  under the Code, and
                    the advice given by the Chief Legal Officer;
               o    report  annually to the Board and the  Corporate  Governance
                    Committee  describing  any issues that arose under the Code,
                    or informing  the Board and Corporate  Governance  Committee
                    that no reportable issues occurred during the year.

         C.       INVESTIGATION PROCEDURES

         The Funds will follow these procedures in  investigating  and enforcing
         this Code:

         o     INITIAL COMPLAINT.  All complaints or other inquiries  concerning
               potential  violations  of the Code must be  reported to the Chief
               Legal Officer.  The Chief Legal Officer shall be responsible  for
               documenting  any  complaint.  The Chief Legal  Officer  also will
               report  immediately  to the  President  of the  Company  (if  the
               complaint involves the Treasurer),  the Chairman of the Board (or
               for the USAA Life Investment Trust (LIT) the Chairman/CEO of USAA
               if the complaint  involves the Chairman of the LIT Board) and the
               Chairperson  of  the  Audit  Committee  any  material   potential
               violations  that  could  have a  material  effect  on the  Funds'
               financial condition or reputation.  For all other complaints, the
               Chief Legal Officer will report quarterly to the Board.
         o     INVESTIGATIONS. The Chief Legal Officer will take all appropriate
               action to investigate any potential violation unless the Chairman
               of the Board or the  Chairperson  of the Audit  Committee  direct
               another person to undertake such  investigation.  The Chief Legal
               Officer  may  utilize  USAA's  Office  of  Ethics to do a unified
               investigation  under this Code and USAA's  Code of  Conduct.  The
               Chairman  of the Board,  or the Board as a whole,  may direct the
               Company's  outside  counsel  or the  counsel  to the  Independent
               Directors/Trustees  (if any) to participate in any  investigation
               under this Code.
         o     STATUS  REPORTS.  The Chief Legal  Officer will  provide  monthly
               status  reports to the Board about any alleged  violation  of the
               Code that could have a  material  effect on the Funds'  financial
               condition or  reputation,  and  quarterly  updates  regarding all
               other alleged violations of the Code.
         o     VIOLATIONS OF THE CODE. If after  investigation,  the Chief Legal
               Officer, or other investigating person, believes that a violation
               of the Code  has  occurred,  he will  report  immediately  to the
               Chairman of the Board (and for the USAA LIT the  Chairman/CEO  of
               USAA if the violation involves the Chairman of the LIT Board) the
               nature of the  violation,  and his  recommendation  regarding the
               materiality  of  the  violation.   If,  in  the  opinion  of  the
               investigating  person,  the violation could materially affect the
               Funds' financial condition or reputation, the Chief Legal Officer
               also will notify the  Chairperson of the Audit  Committee of each
               Company.

               The Chief Legal  Officer will inform,  and make a  recommendation
               to,  the  Board,  which  will  consider  what  further  action is
               appropriate. Appropriate action could include: (1) review of, and
               modifications  to,  the  Code or  other  applicable  policies  or
               procedures; (2) notifications to appropriate personnel of IMCO or
               USAA;  (3)  dismissal  of the Covered  Officer;  and/or (4) other
               disciplinary actions including reprimands or fines.
               o    The Boards of  Directors/Trustees  understand  that  Covered
                    Officers  also  are  subject  to  USAA's  Code  of  Business
                    Conduct.  If a violation of this Code also  violates  USAA's
                    Code of Business  Conduct,  these procedures do not limit or
                    restrict  USAA's ability to discipline  such Covered Officer
                    under USAA's Code of Business  Conduct.  In that event,  the
                    Chairman of the Board of  Directors/Trustees  will report to
                    the  Boards  the  action  taken by USAA  with  respect  to a
                    Covered Officer.

V.       OTHER POLICIES AND PROCEDURES

         This Code  shall be the sole code of  ethics  adopted  by the Funds for
purposes of Section 406 of the Act and the implementing  regulations  adopted by
the SEC  applicable to registered  investment  companies.  If other policies and
procedures of a Company,  IMCO, or other service  providers govern or purport to
govern the behavior or activities of Covered  Officers,  they are  superseded by
this Code to the extent that they  overlap,  conflict  with, or are more lenient
than the  provisions  of this Code.  The USAA  Funds'  and IMCO's  Joint Code of
Ethics under Rule 17j-1 under the 1940 Act, and IMCO's more detailed  compliance
policies and  procedures  (including  its Insider  Trading  Policy) are separate
requirements applying to Covered Officers and other IMCO employees,  and are not
part of this Code. Also, USAA's Code of Conduct imposes separate requirements on
Covered Officers and all employees of USAA, and also is not part of this Code.

VI.      AMENDMENTS

         Any amendment to this Code,  other than  amendments to Appendix A, must
be approved or ratified by majority vote of the Board of Directors/Trustees.

VII.     CONFIDENTIALITY AND DOCUMENT RETENTION

         The Chief Legal Officer shall retain material  investigation  documents
and reports  required to be prepared  under the Code for six years from the date
of the  resolution of any such  complaint.  All reports and records  prepared or
maintained  pursuant to this Code will be considered  confidential  and shall be
maintained  and protected  accordingly.  Except as otherwise  required by law or
this  Code,  such  matters  shall  not be  disclosed  to anyone  other  than the
appropriate  Board  of  Directors/Trustees   and  counsel  for  the  Independent
Directors/Trustees (if any), the appropriate Company and its counsel, IMCO,  and
other  personnel of  USAA as  determined by the  affected  Company's Chief Legal
Officer or the Chairman of the Board of Directors/Trustees.
