               from the PRESIDENT

                                                           "

                                         IT IS A CLASSIC SCENARIO. WHEN MARKETS
[PHOTO OF CHRISTOPHER W. CLAUS]              GO UP, RISK TOLERANCE GOES UP, AND
                                           INVESTORS START TO CHASE PERFORMANCE.

                                                           "

                                                                       June 2006

         Remember risk? It is the flip side of the risk/reward equation. In
         exchange for the possibility of higher returns, you take on more risk.
         But during the last two to three years, many investors have forgotten
         this fundamental investment truth. Hungry for returns in the low-
         interest-rate environment, they flocked into the riskier asset
         classes - the emerging markets, small-cap stocks, precious metals, and
         commodities. Investor experience has been all about reward and very
         little about risk.

         In May, however, risk finally re-emerged as a consideration in
         investment decision-making. Rising global interest rates and the
         potential for a worldwide economic slowdown have led to increased
         market volatility, reminding investors that outsized rewards are
         generally paired with greater risk. As a result, the old adage that
         you should be paid for the risk you assume has taken on renewed
         meaning.

         It is a classic scenario. When markets go up, risk tolerance goes up,
         and investors start to chase performance. The opposite approach is
         often the better course. You would be wise to cultivate patience during
         rising markets and potentially reduce the amount of risk you take.
         Experienced investors know that as market returns increase, so do the
         chances of a correction.

         Still, when the financial markets are awash in liquidity, it is easy
         to forget the fundamentals. If you cannot find the returns you want in
         conservative equity and fixed-income investments, you are tempted to
         seek higher returns elsewhere. This is precisely what happened during
         the last couple of years.

         But in the spring, it all began to unravel as global interest rates
         continued to rise. In the months ahead, we may see even higher
         short-term rates as


                                                                               3

========================--------------------------------------------------------

         the Federal Reserve Board (the Fed) tries to combat inflation. We may
         also see a slowdown in the U.S. economy, and if the U.S. economy cools,
         the world economy is likely to follow suit.

         In this environment, money market fund yields - currently near 5% - are
         appealing, especially for risk-averse investors. Once the Fed pauses,
         bonds should become more attractive. For equity investors, the most
         prudent play may be a conservative stance. They might also want to
         consider locking in some of their gains in the emerging markets, small-
         cap stocks, precious metals, and commodities.

         At USAA Investment Management Company, we have already taken a more
         conservative position in our international and emerging markets
         portfolios - perhaps earlier than a crystal ball would have suggested
         - but as the market has fallen, our relative performance has been
         solid. Going forward, we will continue to look for investment
         opportunities that have the potential to add value while evaluating
         the risks that could affect them.

         From all of us here, thank you for your business and the opportunity to
         serve your investment needs.

         Sincerely,

         /s/ Christopher W. Claus

HOW DID THE FUND PERFORM?

            For the year ended May 31, 2006, the USAA World Growth Fund had a
            total return of 19.00%. This compares to a return of 20.28% for the
            Lipper Global Funds Index and 17.98% for the Morgan Stanley Capital
            International (MSCI) World Index.

CAN YOU DESCRIBE THE GLOBAL EQUITY MARKET ENVIRONMENT OVER THE COURSE OF THE
REPORTING YEAR?

            Overseas markets strongly outperformed United States markets, which
            proved beneficial to shareholders because your Fund was heavily
            underweight in U.S. stocks as a result of our company-by-company
            bottom-up fundamental research. In other words, we didn't make a
            macro decision to have an underweight position in the United
            States; it simply flowed from our analysis of individual stocks.

            PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.

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

            In overseas developed markets, the best performance came from
            Japan, where there were signs that the two-steps-forward, three-
            steps-back economic environment of the past two decades may have
            finally given way to more consistent economic growth. As the year
            progressed, the rally in Japanese stocks spread from exporters and
            banks to companies focused on domestic demand as it began to appear
            that the Japanese consumer might add depth to the recovery. Markets
            in continental Europe performed much better than expected, despite
            a continuation of lackluster economic growth, while emerging
            markets provided the highest returns as a group.

HOW WAS THE FUND POSITIONED?

            We remained underweight in Japan, because although we don't dispute
            that an economic recovery is taking hold, stock prices have moved
            up very quickly, and from a valuation standpoint we believe we're
            finding better opportunities elsewhere. We were overweight in
            continental Europe, slightly overweight in the United Kingdom, and
            had 2.6% of net assets in emerging markets, which are not in the
            MSCI World Index.

            Among our best individual performers relative to the MSCI World
            Index was Schneider Electric S.A. (France), the global leader in
            electrical equipment distribution, which is benefiting from higher
            corporate expenditures on property and equipment. Other stocks
            that did well in the industrial goods and services sector were
            Sweden's Sandvik AB and Atlas Copco AB.

            We had good performance among our financial services holdings, led
            by Goldman Sachs Group, Inc. (U.S.), AXA S.A. (France), and UBS AG
            (Switzerland). In utilities and communications, our holding in
            Hutchison Telecommunications International Ltd. (Hong Kong) did
            well based on its strong position in India's mobile phone market.

            SANDVIK AB AND ATLAS COPCO AB WERE SOLD OUT OF THE FUND PRIOR TO
            MAY 31, 2006.

                         COMMENTARY on the Fund

WHAT AREAS OR HOLDINGS DETRACTED FROM PERFORMANCE?

            Consistent with our philosophy of looking for above-average
            sustainable growth companies, we tended not to own metals and
            mining stocks that benefited from the strong rise in commodity
            prices. This hurt performance in the basic materials sector,
            because we owned more stable growing stocks such as Air Liquide
            S.A. (France) that underperformed the group. The same generally
            holds true in the energy sector, where many of the stocks tend to
            be highly cyclical and therefore don't meet our criteria. For
            instance, we are underweight in global energy giants or energy
            services providers such as Schlumberger Ltd. (U.S.), and obviously
            this proved detrimental because these stocks rode the wave of
            higher energy prices.

WHAT'S YOUR OUTLOOK?

            We continue to see a slowdown in global earnings growth, from
            above-trend levels back to being more in line with long-term
            trends. It's important to recognize that global earnings are very
            high, and it's just harder to show high growth from these levels.
            As earnings slow, we believe the markets tend to reward companies
            that show the ability to sustain above-average earnings growth, and
            we believe we're finding these companies throughout the world and
            in many sectors.

            We thank you, the Fund's shareholders, for your confidence and
            trust.

            SCHLUMBERGER LTD. WAS SOLD OUT OF THE FUND PRIOR TO MAY 31, 2006.

                        DATA FROM 5/31/96 THROUGH 5/31/06.

         The graph illustrates the comparison of a $10,000 hypothetical
         investment in the USAA World Growth Fund to the following benchmarks:

            o  The Lipper Global Funds Index tracks the total return performance
               of the 30 largest funds within the Lipper Global Funds category.

            o  The Morgan Stanley Capital International (MSCI) World Index is an
               unmanaged index that reflects the movements of world stock
               markets by representing a broad selection of domestically listed
               companies within each market.

         PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS, AND THE CUMULATIVE
         PERFORMANCE QUOTED DOES NOT REFLECT THE DEDUCTION OF TAXES THAT A
         SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND
         SHARES.

                         Public ACCOUNTING Firm

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
USAA WORLD GROWTH FUND:

We have audited the accompanying statement of assets and liabilities of the USAA
World Growth Fund (a portfolio of USAA Investment Trust) (the "Fund"), including
the portfolio of investments, as of May 31, 2006, 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 four 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 the period
presented through May 31, 2002, were audited by other auditors whose report,
dated July 5, 2002, expressed an unqualified opinion on those 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, 2006, 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 World Growth Fund at May 31, 2006, 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 four years in
the period then ended, in conformity with U.S. generally accepted accounting
principles.

USAA WORLD GROWTH FUND
MAY 31, 2006

(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 World Growth Fund (the
         Fund), which is classified as diversified under the 1940 Act. The
         Fund's investment objective is capital appreciation.

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

              1. Equity securities, including exchange-traded funds (ETFs),
                 except as otherwise noted, traded primarily on a domestic
                 securities exchange or the Nasdaq over-the-counter markets are
                 valued at the last sales price or official closing price on
                 the exchange or primary market on which they trade. Equity
                 securities traded primarily on foreign securities exchanges or
                 markets are valued at the last quoted sales price, or the most
                 recently determined official price calculated according to
                 local market convention, available at the time the Fund is
                 valued. If no last sale or official closing price is reported
                 or available, the average of the bid and asked prices is
                 generally used.

              2. Equity securities trading in various foreign markets may take
                 place on days when the NYSE is closed. Further, when the NYSE
                 is open, the foreign markets may be closed. Therefore, the
                 calculation of the Fund's net asset value (NAV) may not take
                 place at the same time the prices of certain foreign
                 securities held by the Fund are determined. In most cases,
                 events affecting the values of foreign securities that occur
                 between the time of their last quoted sales or official closing


                                                                              25

                 prices and the close of normal trading on the NYSE on a day
                 the Fund's NAV is calculated will not be reflected in the
                 value of the Fund's foreign securities. However, USAA
                 Investment Management Company (the Manager), an affiliate of
                 the Fund, and the Fund's subadviser, if applicable, will
                 monitor for events that would materially affect the value of
                 the Fund's foreign securities and, if necessary, the Manager
                 will value the foreign securities in good faith, considering
                 such available information that the Manager deems relevant,
                 under valuation procedures approved by the Trust's Board of
                 Trustees. In addition, the Fund may use information from an
                 external vendor or other sources to adjust the foreign market
                 closing prices of foreign equity securities to reflect what
                 the Fund believes to be the fair value of the securities as of
                 the close of the NYSE. Fair valuation of affected foreign
                 equity securities may occur frequently based on an assessment
                 that events that occur on a fairly regular basis (such as U.S.
                 market movements) are significant.

              3. Investments in open-end investment companies, other than ETFs,
                 are valued at their NAV at the end of each business day.

              4. Debt securities purchased with original maturities of 60 days
                 or less are valued at amortized cost, which approximates market
                 value.

              5. Repurchase agreements are valued at cost, which approximates
                 market value.

              6. 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 in good faith at fair value, using methods
                 determined by the Manager in consultation with the Fund's
                 subadviser,

                 if applicable, under valuation procedures approved by the
                 Trust's Board of Trustees. The effect of fair value pricing is
                 that securities may not be priced on the basis of quotations
                 from the primary market in which they are traded and the
                 actual price realized from the sale of a security may differ
                 materially from the fair value price. Valuing these securities
                 at fair value is intended to cause the Fund's 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. Dividend income, less foreign
              taxes, if any, is recorded on the ex-dividend date. If the
              ex-dividend date has passed, certain dividends from foreign
              securities are recorded upon notification. Interest income is
              recorded on the accrual basis. Discounts and premiums on
              short-term securities are amortized on a straight-line basis over
              the life of the respective securities.


                                                                              27

           (continued)

USAA WORLD GROWTH FUND
MAY 31, 2006

           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 U.S.
              government, its agencies, or its instrumentalities. Government-
              sponsored enterprises (GSEs), such as Fannie Mae and 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. FOREIGN CURRENCY TRANSLATIONS - The Fund's assets may be invested
              in the securities of foreign issuers and may be traded in foreign
              currency. Since the Fund's accounting records are maintained in
              U.S. dollars, foreign currency amounts are translated into U.S.
              dollars on the following basis:

              1. Purchases and sales of securities, income, and expenses at the
                 rate of exchange obtained from an independent pricing service
                 on the respective dates of such transactions.

              2. Market value of securities, other assets, and liabilities at
                 the exchange rate obtained from an independent pricing service
                 on a daily basis.

              The Fund does not isolate that portion of the results of
              operations resulting from changes in foreign exchange rates on
              investments from the fluctuations arising from changes in market
              prices of

 N O T E S

           to FINANCIAL Statements
           (continued)

USAA WORLD GROWTH FUND
MAY 31, 2006

              securities held. Such fluctuations are included with the net
              realized and unrealized gain or loss from investments.

              Separately, net realized foreign currency gains/losses may arise
              from sales of foreign currency, currency gains/losses realized
              between the trade and settlement dates on security transactions,
              and from the difference between amounts of dividends, interest,
              and foreign withholding taxes recorded on the Fund's books and
              the U.S. dollar equivalent of the amounts received. At the end of
              the Fund's fiscal year, net realized foreign currency gains/losses
              are reclassified from accumulated net realized gain/loss to
              accumulated undistributed net investment income on the statements
              of assets and liabilities as such amounts are treated as ordinary
              income/loss for tax purposes. Net unrealized foreign currency
              exchange gains/losses arise from changes in the value of assets
              and liabilities, other than investments in securities, resulting
              from changes in the exchange rate.

           F. EXPENSES PAID INDIRECTLY - A portion of the brokerage commissions
              that the Fund pays may be recaptured as a credit that is tracked
              and used by the custodian to directly reduce expenses paid by the
              Fund. In addition, 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, 2006, brokerage commission recapture
              credits and custodian and other bank credits reduced the Fund's
              expenses by $39,000 and $3,000, respectively, resulting in a total
              reduction in Fund expenses of $42,000.

           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


                                                                              29

USAA WORLD GROWTH FUND
MAY 31, 2006

              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) LINE OF CREDIT
- --------------------------------------------------------------------------------

         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, 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
         share of CAPCO's operating expenses related to obtaining and
         maintaining CAPCO's funding programs in total (in no event to exceed
         0.07% 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, 2006, the facility fees
         assessed by CAPCO were limited to an amount not to exceed 0.09%
         annually of the $300 million loan agreement.

USAA WORLD GROWTH FUND
MAY 31, 2006

         For the year ended May 31, 2006, the Fund paid CAPCO facility fees of
         $1,000, which represents 1.1% of total fees paid to CAPCO by the USAA
         funds. The Fund had no borrowings under this agreement during the year
         ended May 31, 2006.

(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 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 resulted in reclassifications to the
         statement of assets and liabilities to increase paid-in capital by
         $1,967,000, increase accumulated undistributed net investment income
         by $68,000, and decrease accumulated net realized gain on investments
         by $2,035,000. This includes differences in the accounting for foreign
         currency gains and losses and the utilization of earnings and profits
         distributed to shareholders on redemption of shares as part of the
         dividends-paid deduction for federal income tax purposes. This
         reclassification has no effect on net assets.

         The tax character of distributions paid during the years ended May 31,
         2006, and 2005, was as follows:



                                                      2006              2005
                                                  -----------------------------
                                                               
Ordinary income*                                  $ 2,618,000        $1,517,000
Long-term realized capital gains                   24,850,000         5,663,000


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


                                                                              31

USAA WORLD GROWTH FUND
MAY 31, 2006

         As of May 31, 2006, the components of net assets representing
         distributable earnings on a tax basis were as follows:


                                                                
Undistributed ordinary income                                      $ 9,688,000
Undistributed long-term capital gains                               22,178,000
Unrealized appreciation of investments                              74,865,000
Unrealized appreciation on foreign currency translations                25,000


         The difference between book-basis and tax-basis unrealized
         appreciation of investments is attributable to the tax deferral of
         losses on wash sales. The difference between book-basis and tax-basis
         appreciation on foreign currency translations is due to the tax
         recognition of gains and losses on foreign currency contracts.

         Distributions of net investment income and 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.

(4) INVESTMENT TRANSACTIONS

         Cost of purchases and proceeds from sales of securities, excluding
         short-term securities, for the year ended May 31, 2006, were
         $175,777,000 and $155,990,000, respectively.

         As of May 31, 2006, the cost of securities, including short-term
         securities, for federal income tax purposes, was $378,442,000.

         Gross unrealized appreciation and depreciation of investments as of
         May 31, 2006, for federal income tax purposes, were $86,309,000 and
         $11,444,000, respectively, resulting in net unrealized appreciation of
         $74,865,000.

(5) FORWARD FOREIGN CURRENCY CONTRACTS
- --------------------------------------------------------------------------------

         The Fund may enter into forward currency contracts to hedge against
         foreign currency exchange risks on the non-U.S. dollar denominated

         securities held in the Fund's portfolio. A forward currency contract
         is an agreement to purchase or sell a specified currency at a
         specified future date or over a specified time period at a price set
         at the trade date of the contract. Forward currency contracts are
         valued on a daily basis using foreign currency exchange rates obtained
         from an independent pricing service. Risks of entering into currency
         contracts include the potential inability of the counterparty to meet
         the terms of the contract and the Fund's giving up the opportunity for
         potential profit.

         At May 31, 2006, the Fund had no open forward foreign currency
         contracts.

(6) 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 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, net of any
         expenses associated with the lending transactions. 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. Wachovia Corp., parent company of
         MetWest, has agreed to indemnify the Fund against any losses due to
         counterparty default in securities-lending transactions.


                                                                              33

MAY 31, 2006

         For the year ended May 31, 2006, the Fund received securities-lending
         income of $185,000, which is net of the 20% income retained by
         MetWest. As of May 31, 2006, the Fund loaned securities having a fair
         market value of approximately $43,194,000, which excluded $41,000 of
         securities on loan that were sold prior to May 31, 2006. The Fund
         received cash collateral of $45,913,000 for the loans. Of this
         amount, $45,852,000 was invested in short-term investments, as noted
         in the Fund's portfolio of investments, and $61,000 remained in cash.

(7) TRANSACTIONS WITH MANAGER
- --------------------------------------------------------------------------------

      A. MANAGEMENT FEES - The Manager provides investment management
         services to the Fund pursuant to an Investment Advisory Agreement.
         Under this agreement, the Manager is responsible for managing the
         business and affairs of the Fund, subject to the authority of and
         supervision by the Trust's Board of Trustees. The Manager is
         authorized to select (with approval of the Trust's Board of Trustees)
         one or more subadvisers to manage the actual day-to-day investment of
         the Fund's assets. The Manager monitors each subadviser's performance
         through quantitative and qualitative analysis, and periodically
         recommends to the Trust's Board of Trustees as to whether each
         subadviser's agreement should be renewed, terminated, or modified. The
         Manager also is responsible for allocating assets to the subadvisers.
         The allocation for each subadviser can range from 0% to 100% of the
         Fund's assets, and the Manager can change the allocations without
         shareholder approval.

         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 Global Funds Index, which tracks the total return
         performance of the 30 largest funds in the

           to FINANCIAL Statements
           (continued)

USAA WORLD GROWTH FUND
MAY 31, 2006

         Lipper Global Funds category. The Fund's base fee is accrued daily and
         paid monthly at an annualized rate of 0.75% of the Fund's average net
         assets for the fiscal year.

         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 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
RELATIVE TO INDEX(1)                     AS A % OF THE FUND'S AVERAGE NET ASSETS
- --------------------------------------------------------------------------------
                                      
+/- 1.00% to 4.00%                       +/- 0.04%

+/- 4.01% to 7.00%                       +/- 0.05%

+/- 7.01% 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 Global Funds Index over that period, even if
         the Fund had overall negative returns during the performance period.

         For the year ended May 31, 2006, the Fund incurred total management
         fees, paid or payable to the Manager, of $2,695,000, which included a
         performance adjustment of $(40,000) that decreased the base management
         fee of 0.75% by 0.01%.


                                                                              35

           B. SUBADVISORY ARRANGEMENTS - The Manager has entered into an
              investment subadvisory agreement with MFS Investment Management
              (MFSIM), under which MFSIM directs the investment and reinvestment
              of the Fund's assets (as allocated from time to time by the
              Manager). Effective January 3, 2006, the Manager (not the Fund)
              pays MFSIM a subadvisory fee in the annual amount of 0.29% of the
              Fund's average net assets that MFSIM manages. Prior to January 3,
              2006, the Manager (not the Fund) paid MFSIM a subadvisory fee
              based on the aggregate average net assets that MFSIM managed in
              the USAA World Growth Fund, the USAA International Fund, the USAA
              Life Investment Trust World Growth Fund, and the USAA Cornerstone
              Strategy Fund combined (MFSIM Funds), in the annual amount of
              0.335% of the first $350 million of assets, plus 0.225% of assets
              over $350 million but not over $1 billion, plus 0.200% of assets
              over $1 billion. For the year ended May 31, 2006, the Manager
              incurred subadvisory fees for the Fund, paid or payable to MFSIM,
              of $968,000.

           C. 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, 2006, the Fund incurred
              administration and servicing fees, paid or payable to the
              Manager, of $547,000.

              In addition to the services provided under its Administration and
              Servicing Agreement with the Fund, the Manager also provides
              certain legal and tax services for the benefit of the Fund. The
              Trust's Board of Trustees has approved the reimbursement of these
              expenses incurred by the Manager. For the year ended May 31,
              2006, the Fund reimbursed the Manager $20,000 for

              these legal and tax services. These expenses are included in the
              professional fees expenses on the Fund's statement of operations.

           D. TRANSFER AGENT'S FEES - USAA Transfer Agency Company, d/b/a USAA
              Shareholder Account Services (SAS), an affiliate of the Manager,
              provides transfer agent services to the Fund based on an annual
              charge of $23 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, 2006, the Fund incurred transfer agent's
              fees, paid or payable to SAS, of $889,000. Additionally, the Fund
              recorded a receivable from SAS of $1,000 at May 31, 2006, for
              adjustments to dividends payable.

           E. 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.

(8) 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.

               EXAMPLE (unaudited)

USAA WORLD GROWTH FUND
MAY 31, 2006

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, 2005, through May 31, 2006.

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


                                                                              39

               (continued)

USAA WORLD GROWTH FUND
MAY 31, 2006

         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

MAY 31, 2006

         At a meeting of the Board of Trustees held on April 19, 2006, 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 and the Subadvisory Agreement 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 Subadvisory Agreement and the Manager and the Subadviser, 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 and Subadviser's operations and personnel. Prior
         to voting, the Independent Trustees reviewed the proposed continuance
         of the Investment Advisory Agreement and the Subadvisory 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 and the Subadvisory Agreement with respect to the Fund. The
         Independent Trustees also reviewed the proposed continuation of the
         Investment Advisory Agreement and the Subadvisory 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 and by the Subadviser. At the meeting
         at which the renewal of the Investment Advisory Agreement and
         Subadvisory


                                                                              41

         Agreement is considered, particular focus is given to information
         concerning Fund performance, comparability of fees and total expenses,
         and profitability. However, the Board noted that the evaluation
         process with respect to the Manager and the Subadviser is an ongoing
         one. In this regard, the Board's and its committees' consideration of
         the Investment Advisory Agreement and Subadvisory Agreement included
         certain information previously received at such quarterly meetings.

INVESTMENT ADVISORY AGREEMENT
- --------------------------------------------------------------------------------

         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.

USAA WORLD GROWTH FUND
MAY 31, 2006

         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
         Board discussed the Manager's effectiveness in monitoring the
         performance of the Subadviser and its timeliness in responding to
         performance issues. 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
         objective and classification, sales load type (in this case,
         investment companies with no sales loads), asset size, and expense


                                                                              43

         components (the "expense group") and (ii) a larger group of investment
         companies that includes all no-load retail open-end investment
         companies in the same investment classification/objective 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 below the median of both its
         expense group and its expense universe. The data indicated that the
         Fund's total expenses were below the median of both its expense group
         and 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. The Trustees also
         took into account that the subadvisory fees under the Subadvisory
         Agreement are paid by the Manager.

         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 was below the average of its Lipper index for the
         one-, three-, and five-year periods ended December 31, 2005, was below
         the average of its performance universe for the one- and three-year
         periods ended December 31, 2005, and was above the average of its
         performance universe for the five-year period ended December 31, 2005.
         The Board also noted that

         the Fund's percentile performance ranking was in the bottom 50% of its
         performance universe for the one- and three-year periods ending
         December 31, 2005. The Board took into account management's discussion
         of the factors that contributed to the Fund's performance and the
         steps to be taken to address such performance.

         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.
         In considering the profitability data with respect to the Fund, the
         Trustees noted that the Manager pays the subadvisory fees. 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.

         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. The Board took into
         account management's discussion of the current advisory fee structure.
         The Board also noted that the Fund's contractual management fees are
         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


                                                                              45

         party. The Board also considered the effect of the Fund's growth and
         size on its performance and fees, noting that if the Fund's assets
         increase over time, the Fund may realize other economies of scale if
         assets increase proportionally more than some expenses. 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 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 being
         addressed; (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 their conclusions,
         the Board determined that continuation of the Investment Advisory
         Agreement would be in the interests of the Fund and its shareholders.

SUBADVISORY AGREEMENT
- --------------------------------------------------------------------------------

         In approving the Fund's Subadvisory Agreement, the Board considered
         various factors, among them: (i) the nature, extent, and quality of
         services provided to the Fund, including the personnel providing
         services; (ii) the Subadviser's compensation and any other benefits
         derived from the subadvisory relationship; (iii) comparisons of
         subadvisory fees and performance to comparable investment companies;
         and (iv) the terms of the Subadvisory Agreement. The Board's analysis
         of these factors is set forth below.

         After full consideration of a variety of factors, the Board of
         Trustees, including the Independent Trustees, voted to approve the
         Subadvisory Agreement. In approving the Subadvisory 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 PROVIDED; INVESTMENT PERSONNEL.
         The Trustees considered information provided to them regarding the
         services provided by the Subadviser, including information presented
         periodically throughout the previous year. The Board considered the
         Subadviser's level of knowledge and investment style. The Board
         reviewed the experience and credentials of the investment personnel
         who are responsible for managing the investment of portfolio
         securities with respect to the Fund and the Subadviser's level of
         staffing. The Trustees noted that the materials provided to them
         indicated that the method of compensating portfolio managers is
         reasonable and includes appropriate mechanisms to prevent a manager
         with underperformance from taking undue risks. The Trustees also noted
         the Subadviser's brokerage practices. The Board also considered the
         Subadviser's regulatory and compliance history. The Board noted that
         the Manager's monitoring processes of the Subadviser include: (i)
         regular telephonic meetings to discuss, among other matters,
         investment strategies and to review portfolio performance; (ii)
         monthly portfolio compliance checklists and quarterly compliance
         certifications to the Board; and (iii) due diligence visits to the
         Subadviser.

         SUBADVISER COMPENSATION. The Board also took into consideration the
         financial condition of the Subadviser. In considering the cost of
         services to be provided by the Subadviser and the profitability to the
         Subadviser of its relationship with the Fund, the Trustees noted the
         undertakings of the Manager to maintain expense limitations for the
         Fund and also noted that the fees under the Subadvisory Agreement were
         paid by the Manager. The Trustees also relied on the ability of the
         Manager to negotiate the Subadvisory Agreement and the fees thereunder
         at arm's length. The Board also considered information relating to the
         cost of services to be provided by the Subadviser, the Subadviser's
         profitability


                                                                              47

         with respect to the Fund, and the potential economies of scale in the
         Subadviser's management of the Fund, to the extent available. However,
         for the reasons noted above, this information was less significant to
         the Board's consideration of the Subadvisory Agreement than the other
         factors considered.

         SUBADVISORY FEES AND FUND PERFORMANCE. The Board compared the
         subadvisory fees for the Fund with the fees that the Subadviser
         charges to comparable clients. The Board considered that the Fund pays
         a management fee to the Manager and that, in turn, the Manager pays a
         subadvisory fee to the Subadviser.

         As noted above, the Board considered the Fund's performance during the
         one-, three-, and five-year periods ended December 31, 2005, as
         compared to the Fund's respective peer group and noted that the Board
         reviews at its regularly scheduled meetings information about the
         Fund's performance results. The Board noted the Manager's expertise
         and resources in monitoring the performance, investment style, and
         risk-adjusted performance of the Subadviser. The Board was mindful of
         the Manager's focus on the Subadviser's performance and the
         explanations of management regarding the factors that contributed to
         the short-term performance of the Fund. The Board also noted the
         Subadviser's long-term performance record for similar accounts.

         CONCLUSION. The Board reached the following conclusions regarding the
         Subadvisory Agreement, among others: (i) the Subadviser is qualified
         to manage the Fund's assets in accordance with its investment
         objectives and policies; (ii) the Subadviser maintains an appropriate
         compliance program; (iii) the performance of the Fund is being
         addressed; and (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 the Subadviser. Based on the Board's conclusions,
         the Board of Trustees determined that approval of the Subadvisory
         Agreement with respect to the Fund 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.  On  September  14,  2005,  the Board of  Trustees of USAA
Investment  Trust  approved a revised  Sarbanes  Code  applicable  to the Funds'
senior  financial  officers.  There were no  substantive  changes to the ethical
duties or responsibilities of the Funds' senior financial officers.  The changes
to the Sarbanes Code were necessary because of the change of the Funds' Chairman
of the Board to an  independent  director.  The revised  Sarbanes Code clarifies
that the same USAA personnel will continue to receive  reports of all violations
of the Sarbanes Code and be required to approve  outside  employment and certain
financial interests in transactions. Under the revised Sarbanes Code, the Funds'
Board of Directors will continue to receive the same notifications,  reports and
have the same power that it had before under the original  Sarbanes Code. A copy
of the revised Sarbanes Code is attached as an Exhibit to this Form N-CSR.

No  waivers (explicit  or  implicit)  have been  granted from a provision of the
Sarbanes Code or the revised Sarbanes Code.



ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

Finance at the  University of Texas at Austin since 1987,  and has served as the
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 and an expert witness in cases involving
financial reporting matters.  Dr. Starks is an independent trustee who serves as
a member  of the Audit  Committee,  Pricing  and  Investment  Committee  and the

(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.

$109,143, respectively.

(h) Ernst & Young LLP provided  non-audit services to IMCO in 2006 and 2005 that

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.

The  principal  executive  officer  and  principal  financial  officer  of  USAA

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.

                         FOR PRINCIPAL EXECUTIVE OFFICER
                          AND SENIOR FINANCIAL OFFICERS

                             USAA MUTUAL FUND, INC.
                           USAA TAX-EXEMPT FUND, INC.
                              USAA INVESTMENT TRUST
                             USAA MUTUAL FUNDS 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 Mutual Funds 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:
             -  honest and ethical conduct, including the ethical handling of
                actual or apparent conflicts of interest between the Covered
                Officers' personal and professional relationships;
             -  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;
             -  compliance with applicable laws and governmental rules and
                regulations;
             -  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), the Chair/CEO of USAA,
                and if deemed material to the Funds' financial condition or
                reputation, the Chair of the relevant Funds' Board of Directors/
                Trustees; and
             -  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:

         -  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;
         -  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.
         -  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.
         -  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:

         -  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.
         -  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.
         -  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.
         -  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 Chair/
            CEO of USAA and reported to each affected Board.
         -  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 Chair/CEO
            of USAA and reported to each affected Board.

III.     DISCLOSURE AND COMPLIANCE REQUIREMENTS
         --------------------------------------

         -  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.
         -  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.
         -  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.
         -  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.
         -  A Covered Officer should not retaliate against any person who
            reports a potential violation of this Code in good faith.
         -  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 Chair/CEO of
                USAA and will be considered by the Board of Directors/Trustees.

         B.     REQUIRED REPORTS
                ----------------

                -      EACH COVERED OFFICER MUST:
                       -------------------------

                       -      Upon adoption of the Code, affirm in writing to
                              the Boards that he has received, read and
                              understands the Code.
                       -      Annually thereafter affirm to the Chief Legal
                              Officer that he has complied with the requirements
                              of the Code.

                -      THE CHIEF LEGAL OFFICER MUST:
                       ----------------------------

                       -      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;
                       -      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:

         -        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/CEO  of USAA  and the  Chair of the  relevant  Funds'
                  Audit Committee (if the complaint  involves the President) 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.
         -        INVESTIGATIONS.   The  Chief  Legal   Officer  will  take  all
                  appropriate  action to  investigate  any  potential  violation
                  unless  the  Chair/CEO  of  USAA  directs  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 Chief Legal
                  Officer  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.
         -        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.
         -        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 Chair/CEO of USAA 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 Chair
                  of the  relevant  Funds'  Audit  Committee.  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 Boards 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.
