               from the PRESIDENT

                                                            "

                                                                       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

                   COMMENTARY on the Fund

HOW DID THE FUND PERFORM?

         For the year ended May 31, 2006, the USAA GNMA Trust had a total
         return of 0.40%. This compares to a 0.10% return for the Lipper GNMA
         Funds Index and 0.72% for the Lehman Brothers GNMA 30-Year Index.

WHAT WAS THE MARKET ENVIRONMENT DURING THE PERIOD?

         The Federal Reserve Board (the Fed) continued to raise short-term
         interest rates; by the end of May 2006, the federal funds rate stood
         at 5%, up from a low of 1% in June 2004. Unlike the previous reporting
         year, when long-term rates remained stubbornly low in the face of Fed
         hikes, long-term rates moved up substantially, although not as much as
         short-term rates. The yield on the benchmark 10-year U.S. Treasury
         bond rose from 3.98% on May 31, 2005, to 5.12% a year later (see chart
         on next page).

         Partially driving the Fed's decision-making were the strong U.S.
         economy and occasional signs of inflation. Some indications of an
         economic slowdown began to appear during the latter part of the
         period. We've noted before that there's a lag between Fed rate hikes
         and their impact on the economy. It's our view that the cumulative
         effects of two years of sustained tightening are beginning to be felt.

         PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.

HOW DID MORTGAGE-BACKED SECURITIES PERFORM?

         Mortgage-backed securities outperformed the overall bond market. One
         reason is that mortgage-backed securities have interest-rate
         sensitivity similar to that of short- to intermediate-term bonds.
         Even though mortgage-backed securities have 15- or 30-year final
         maturities, they are paid off when a mortgage is refinanced or a house
         is sold, giving mortgages a weighted average life that is
         substantially less than the final maturity. Another performance driver
         was the fact that there is no risk of leveraged buyouts (LBOs) in GNMA
         securities (GNMAs) as there is in corporate bonds. In an LBO, a
         private equity fund can take a corporation private at the expense of
         current bondholders. Finally, we saw substantial foreign buying of
         GNMAs. Foreigners are

         attracted to GNMAs because of their U.S. government guarantee. In the
         first part of the reporting year, foreign buying pushed valuations to
         very high levels relative to other mortgage-backed securities. But in
         2006, foreign buying has cooled, leaving GNMAs at more reasonable
         levels, although still high by historical standards.

HOW DID YOU MANAGE THE FUND IN THIS ENVIRONMENT?

         Concerned about rising interest rates, we began the year with a
         strategy of maintaining a relatively short duration (a measure of
         interest-rate sensitivity). We achieved this by buying higher-coupon
         bonds and keeping some assets in cash equivalents. About halfway
         through the reporting year, we began to extend duration through
         purchases of lower-coupon mortgages, and by the end of the period the
         Fund's interest-rate sensitivity was fairly


                                                                               7

         close to neutral. When foreign buying pushed GNMA prices to levels
         that, in our view, were too high, we restricted new purchases to
         Fannie Mae and Freddie Mac mortgage-backed securities. By the end of
         the period, we were taking advantage of the four-year highs in
         long-term rates to purchase additional securities.

WHAT'S YOUR OUTLOOK?

         Although data on jobs, retail sales, home prices, and manufacturing
         are finally giving signs that economic growth is slowing, it's still
         difficult to say when the Fed will stop raising short-term rates. Our
         view is that the economy will continue to cool, with housing being a
         key factor. In the last three years, rising residential real estate
         prices have allowed consumers to maintain their spending by cashing
         out equity in their homes. Flat to lower home prices, therefore, could
         dampen consumer spending and slow employment growth, because so many
         of the new jobs that have been created are in housing-related
         industries.

                         COMMENTARY on the Fund

         As we move into the new reporting year, risk reduction seems to be the
         new investment theme. GNMAs should benefit from this emphasis because
         they are among the safest securities. Of course, for investors in this
         Fund, it's all about earning income. Although the net asset value will
         fluctuate, we believe long-term investors should focus on total return
         and steady income.

COULD THE HOUSING SLOWDOWN HAVE AN IMPACT ON THE FUND?

         GNMAs are backed by the full faith and credit of the U.S. government.
         If a mortgage-holder defaults on a mortgage in a GNMA pool, the
         investor will receive all of the principal back. Regardless of
         housing prices, GNMAs are as safe from a credit-risk perspective as
         U.S. Treasuries. Indirectly, a housing slowdown could potentially be a
         catalyst for lower interest rates and a less-aggressive Fed, which,
         we believe, would be positive for the bond market overall.

         On behalf of everyone at USAA, we thank you for your investment in the
         Fund.

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

         The graph illustrates the comparison of a $10,000 hypothetical
         investment in the USAA GNMA Trust to the following benchmarks:

         o  The Lehman Brothers GNMA 30-Year Index is an unmanaged index of
            pass-through securities with an original maturity of 30 years.

         o  The Lipper GNMA Funds Index tracks the total return performance of
            the 10 largest funds within the Lipper GNMA Funds category.

         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 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, 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 GNMA Trust 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.

GENERAL NOTES
- --------------------------------------------------------------------------------

         Market values of securities are determined by procedures and practices
         discussed in Note 1 to the financial statements.

         The portfolio of investments category percentages shown represent the
         percentages of the investments to net assets and, in total, may not
         equal 100%.

SPECIFIC NOTES
- --------------------------------------------------------------------------------

         (a) U.S. government agency issues - mortgage-backed securities issued
             by Government National Mortgage Association (GNMA) are supported
             by the full faith and credit of the U.S. government. Securities
             issued by government-sponsored enterprises (GSEs) indicated with
             "+" are supported only by the credit of the issuing agency,
             instrumentality, or corporation, and are neither issued nor
             guaranteed by the U.S. government.

         (b) Collateral on repurchase agreements is received by the Fund upon
             entering into the repurchase agreement. The collateral is marked-
             to-market daily to ensure its market value is equal to or in excess
             of the repurchase agreement price plus accrued interest.

         (c) At May 31, 2006, the aggregate market value of securities purchased
             on a delayed-delivery basis was $14,929,000.

         (d) At May 31, 2006, a portion of this security was segregated to
             cover when-issued securities.

USAA GNMA TRUST
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 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 valued at amortized cost, which approximates market
                 value.

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

              4. 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


                                                                              25

           (continued)

USAA GNMA TRUST

                 valued 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. 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 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.

           (continued)

              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. SECURITIES PURCHASED ON A DELAYED-DELIVERY OR WHEN-ISSUED BASIS -
              Delivery and payment for securities that have been purchased by
              the Fund on a delayed-delivery or 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 delayed-delivery or
              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. As of May 31, 2006, outstanding
              delayed-delivery commitments, including interest purchased where
              applicable, for the Fund were $29,901,000, which included when-
              issued securities of $14,899,000. Also outstanding was a same-day
              sale of a when-issued commitment of $14,875,000.

           F. EXPENSES PAID INDIRECTLY - Through arrangements with the Fund's
              custodian and other banks utilized by the Fund for cash


                                                                              27

 N O T E S

           to FINANCIAL Statements
           (continued)

USAA GNMA TRUST
MAY 31, 2006

              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, these custodian
              and other bank credits reduced the Fund's expenses by $4,000.

           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) 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.

         For the year ended May 31, 2006, the Fund paid CAPCO facility fees of
         $1,000, which represents 1.8% 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 for security paydowns resulted in
         reclassifications to the statement of assets and liabilities to
         increase accumulated undistributed net investment income and increase
         accumulated net realized loss on investments by $3,155,000. 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*               $28,404,000       $28,942,000

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


                                                                              29

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

         Undistributed ordinary income                            $    425,000
         Accumulated capital and other losses                      (42,743,000)
         Unrealized depreciation of investments                    (16,485,000)


         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. At May 31, 2006, the Fund had a current post-October
         deferred capital loss of $1,524,000 and capital loss carryovers of
         $41,219,000, 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 2014, as shown below. It is unlikely that
         the Trust's Board of Trustees will authorize a distribution of capital
         gains realized in the future until the capital loss carryovers have
         been utilized or expire.

(4) INVESTMENT TRANSACTIONS
- --------------------------------------------------------------------------------

         Cost of purchases and proceeds from sales/maturities of securities,
         excluding short-term securities, for the year ended May 31, 2006, were
         $145,384,000 and $175,225,000, respectively.

         As of May 31, 2006, the cost of securities, including short-term
         securities, for federal income tax purposes, was $551,141,000.

         Gross unrealized appreciation and depreciation of investments as of
         May 31, 2006, for federal income tax purposes, were $1,503,000 and
         $17,988,000, respectively, resulting in net unrealized depreciation of
         $16,485,000.

(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 securities loaned, initially in an amount at
         least equal to 102% of the fair value of domestic 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. The Fund had
         no securities-lending transactions during the year ended May 31, 2006.


                                                                              31

(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
              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
- ---------------------------------------------------------------------------------
                                       
+/- 0.20% to 0.50%                        +/- 0.04%
+/- 0.51% to 1.00%                        +/- 0.05%
+/- 1.01% and greater                     +/- 0.06%

   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, 2006, the Fund incurred total
              management fees, paid or payable to the Manager, of $708,000,
              which included no performance adjustment.

           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, 2006, the Fund incurred
              administration and servicing fees, paid or payable to the Manager,

              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 $21,000 for these legal and tax
              services. These expenses are included in the professional fees
              expenses on the Fund's statement of operations.

           C. 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 $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, 2006, the Fund incurred
              transfer agent's fees, paid or payable to SAS, of $876,000.


                                                                              33

           D. UNDERWRITING SERVICES - The Manager provides exclusive

         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

         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, 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.

         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 of

         fees and total expenses, and profitability. However, the Board noted
         that the evaluation process with respect to the Manager is an ongoing
         one. In this regard, the Board's and its committees' consideration of
         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


                                                                              39

         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 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.

         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, 2005. The Board also noted that the Fund's percentile
         performance ranking was in the top 30% and top 50% of its performance
         universe for the one-and three-year periods, respectively, ended
         December 31, 2005.

         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


                                                                              41

         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. 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 discussions of the current advisory fee
         structure. 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
         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.


                                                                              43

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.

Dr. Laura T. Starks,  Ph.D. has been designated as an audit committee  financial
expert for USAA  Investment  Trust.  Dr.  Starks has  served as a  professor  of
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
Corporate  Governance  Committee  of the Board of  Trustees  of USAA  Investment
Trust. Dr. Starks resigned from the Board of Trustees effective May 22, 2006.

for audit related services  related to the annual study of internal  controls of
the transfer agent for fiscal years ended May 31, 2006 and 2005 were $50,000 and
$15,500, respectively. All services were preapproved by the Audit Committee.

(c)  TAX  FEES.  The aggregate  fees  paid or  accrued  by  the  Registrant  for
professional  services  rendered  by Ernst &  Young,  LLP for tax  services  are
detailed in the table below:

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

years ended May 31, 2006 or 2005.

(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.

(g) The  aggregate  non-audit  fees  billed  by Ernst & Young  LLP for  services
rendered to the Registrant and the Registrant's  investment  adviser,  IMCO, and
the Funds'  transfer  agent,  SAS,  for May 31, 2006 and 2005 were  $187,642 and
$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.

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

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 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.
