               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

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

         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 Cornerstone Strategy
                 Fund had a total return of 8.67%. This compares to a return of
                 14.81% for the Lipper Global Flexible Funds Index and 8.63%
                 for the S&P 500 Index.

HOW WAS THE FUND ALLOCATED AMONG THE VARIOUS ASSET CLASSES?

                 The Fund began the reporting year with 52% of net assets in
                 U.S. equities, 29% in international equities, and 19% in bonds
                 and money market instruments. Due to asset allocation
                 adjustments and investment performance, the Fund ended the
                 fiscal year with 42% of net assets in U.S. equities, 29% in
                 international equities, 27% in bonds and money market
                 instruments, 1% in precious metals and minerals securities,
                 and 1% in real estate equity securities.

                 PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS.

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

WHY DID THE FUND UNDERPERFORM ITS LIPPER PEER GROUP INDEX?

                 First, there was underperformance within the U.S. equity
                 portion of the Fund relative to the Lipper Global Flexible
                 Funds Index. Also, the Fund was underweight in international
                 stocks in a period when international stocks significantly
                 outperformed U.S. stocks. Finally, the Fund had an underweight
                 position in stocks overall, both in the United States and
                 overseas, in a period when stocks outperformed bonds by a good
                 margin.

WERE ANY STEPS TAKEN TO IMPROVE PERFORMANCE?

                 Yes, USAA Investment Management Company (USAA IMCO) and the
                 Fund's Board of Trustees made several key decisions during the
                 reporting year that we believe will ultimately enhance
                 long-term performance, increase flexibility and efficiency,
                 and potentially reduce risk. These include:

                 o  In December 2005, Batterymarch Financial Management,
                    Inc. (Batterymarch) began subadvising a portion of the
                    Fund's assets using a "best ideas" global investment
                    strategy, purchasing stocks that its stock-selection model
                    has ranked the most attractive in the global marketplace.
                    Instead of being tied to just one stock style in one
                    country, Batterymarch can scour the world on your behalf
                    for what it believes are the best investments in each global
                    industry sector.

                 o  Effective March 1, 2006, the Fund's Board of Trustees
                    voted to increase the international stocks category limit
                    from 30% to 70%.

                 o  The Fund increased its utilization of exchange-traded funds
                    (ETFs) for cost efficiency and investment flexibility. ETFs,
                    relatively low-cost vehicles that typically track a market
                    index, give us the ability to adjust the Fund's asset
                    allocation quickly when USAA IMCO believes it is warranted.
                    At the end of the

                         COMMENTARY on the Fund

                    reporting year, 13.7% of the Fund's net assets were in ETFs
                    tied to the U.S. stock market.

HOW DID THE U.S. STOCK PORTION OF THE FUND THAT WELLINGTON MANAGEMENT COMPANY,
LLP (WELLINGTON) MANAGES PERFORM?

                 The Wellington-managed portion of the Fund underperformed the
                 Russell 3000 Index. While stock selection was positive
                 relative to the Russell 3000 Index, sector allocation
                 detracted from relative performance.  Energy was the
                 top-performing area of the market, and the Fund benefited from
                 overweight exposure to this sector, with Schlumberger Ltd.,
                 Chesapeake Energy Corp., and GlobalSantaFe Corp. among the top
                 positive contributors to performance. Industrials company
                 Precision Castparts Corp. delivered excellent performance with
                 strong fundamental growth. In the financials sector, many of
                 our capital markets-related stocks, including E*TRADE
                 Financial Corp., Merrill Lynch & Co., Inc., and State Street
                 Corp., outperformed on a relative basis.

                 Stock selection in information technology, health care, and
                 utilities detracted from relative performance in the portion
                 of the Fund that Wellington managed. Adobe Systems, Inc. was
                 our weakest-performing stock, because the company was between
                 product cycles and struggled to meet its revenue and earnings
                 targets. However, we view this as a short-term concern because
                 the new version of the hugely popular Adobe Acrobat remains on
                 track for a fall 2006 release. Dell, Inc., Yahoo!, Inc., and

                 THE RUSSELL 3000 INDEX MEASURES THE PERFORMANCE OF THE 3,000
                 LARGEST U.S. COMPANIES BASED ON TOTAL MARKET CAPITALIZATION,
                 WHICH REPRESENTS APPROXIMATELY 98% OF THE INVESTABLE U.S.
                 EQUITY MARKET. WELLINGTON AND USAA IMCO UTILIZE THE RUSSELL
                 3000 AS A FINANCIAL MARKET PERFORMANCE BENCHMARK IN MANAGING
                 THE U.S. STOCK PORTION OF THE FUND.

                 GLOBALSANTAFE CORP., DELL, INC., YAHOO!, INC., TEMPUR-PEDIC
                 INTERNATIONAL, INC., AND KOHL'S CORP. WERE SOLD OUT OF THE
                 FUND PRIOR TO MAY 31, 2006.

                 Microsoft Corp. also hurt performance, as did the mattress
                 company Tempur-Pedic International, Inc., the retailer Kohl's
                 Corp., and biotechnology giant Amgen, Inc.

                 As of the end of the reporting year, the portion of the
                 portfolio that Wellington manages was overweight in the health
                 care and consumer discretionary sectors, where we have been
                 finding stocks with attractive valuations and good relative
                 earnings potential. We were modestly overweight in energy as
                 global demand and constrained supply foster long-term growth
                 prospects. We also maintained an overweight position in
                 information technology, with an emphasis on software
                 companies, which should benefit from higher corporate spending
                 amid new product cycles. We were underweight in utilities,
                 which appear expensive on a price-to-earnings basis and less
                 attractive on a yield basis given our modestly higher
                 interest-rate outlook.

HOW DID THE INTERNATIONAL STOCK PORTION OF THE FUND THAT MFS INVESTMENT
MANAGEMENT (MFS) HANDLES PERFORM?

                 The MFS-managed portion of the Fund underperformed the Morgan
                 Stanley Capital International Europe, Australasia and Far East
                 (MSCI-EAFE) Index. As a result of a company-by-company
                 bottom-up research process, 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
                 2.8% of net assets in emerging markets, which are not in the
                 MSCI-EAFE Index.

                 Among the best individual performers in the MFS-managed
                 portion of the Fund relative to the MSCI-EAFE Index was

                 THE MSCI-EAFE INDEX IS AN UNMANAGED INDEX THAT REFLECTS THE

                 EAST BY REPRESENTING A BROAD SELECTION OF DOMESTICALLY LISTED
                 COMPANIES WITHIN EACH MARKET.

                 sector were Sweden's Sandvik AB and Atlas Copco AB. In
                 utilities and communications, our holding in Hutchison
                 Telecommunications International Ltd. (Hong Kong) did well
                 based on its strong position in the mobile phone market in
                 India.  Although we were underweight in the strong energy
                 sector, we had very positive stock selection, led by EnCana
                 Corp. (Canada) and CNOOC Ltd.  (China).

                 Consistent with the MFS 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. Higher commodity prices also had a negative
                 impact on our overweight position in Bridgestone Corp.
                 (Japan). In consumer staples, our substantially overweight
                 position in Nestle S.A. (Switzerland) detracted from
                 performance on a relative basis.

                 We at MFS continue to see a slowdown in global earnings
                 growth, from above-trend levels back to being more in line
                 with long-term trends.  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 for the MFS portion of the Fund.

HOW DID THE PORTION OF THE FUND THAT BATTERYMARCH MANAGES PERFORM?

                 With the ability to purchase the stocks that its stock
                 selection model has ranked as most attractive, from anywhere
                 in the world, the portion of the Fund that Batterymarch
                 manages significantly

                 THE 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.

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


                                                                               9

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

                 outperformed the MSCI World Index from its introduction into
                 the Fund in early December.

                 Batterymarch intentionally keeps the industry sector
                 weightings of its portion of the Fund approximately in line
                 with the MSCI World Index as a risk-management tool, and
                 therefore individual stock selection was the key to the strong
                 performance. Performance during the period was helped by stock
                 selection in the industrials, information technology,
                 financials (excluding banks), energy, and consumer staples
                 sectors, with Vallourec S.A., a French carbon steel
                 manufacturer, and LUKoil Holdings ADR, a Russian oil company,
                 among the top contributors.  Exposure within the 11 global
                 economic sectors was a result of bottom-up stock selection, as
                 opposed to any top-down macro views.

                 The Batterymarch stock selection model, which ranks a very
                 broad stock universe, led us to end the reporting year with
                 greater exposure to the value-oriented end of the spectrum for
                 the Batterymarch portion of the Fund. This positioning
                 reflects the fact that our model ranks stocks based on
                 underlying company fundamentals; as these fundamentals shift,
                 our goal is to shift with them. Batterymarch re-ranks all
                 stocks daily, an approach that allows us to make investment
                 decisions based on the most up-to-date information available.

HOW DID THE FUND'S BOND AND MONEY MARKET INSTRUMENTS, A USAA
IMCO-MANAGED-PORTION, PERFORM?

                 It's hard for most people to be excited about performance when
                 you barely manage to break even, as was the case with the bond
                 portion during the reporting year. However, this represented
                 outstanding performance relative to the Lehman Brothers U.S.
                 Aggregate Bond Index.

                 THE LEHMAN BROTHERS U.S. AGGREGATE BOND INDEX COVERS THE U.S.
                 INVESTMENT-GRADE FIXED-RATE BOND MARKET, INCLUDING GOVERNMENT
                 AND CREDIT SECURITIES, AGENCY MORTGAGE PASS-THROUGH
                 SECURITIES, ASSET-BACKED SECURITIES, AND COMMERCIAL
                 MORTGAGE-BACKED SECURITIES THAT HAVE REMAINING MATURITIES OF
                 MORE THAN ONE YEAR.

 . . . C O N T I N U E D
========================--------------------------------------------------------
                         COMMENTARY on the Fund

                 It was a tough environment for bonds as interest rates rose
                 across all maturities on the yield curve, but USAA IMCO
                 managed to provide a positive total return as interest on the
                 bonds we owned offset the principal erosion caused by rising
                 rates. A key factor in our good performance was our strategy
                 regarding duration, a measure of interest-rate sensitivity.
                 We began the year with a shorter-than-average duration, and
                 gradually moved toward a neutral duration. Throughout the
                 reporting year, we were opportunistic, buying when rates rose
                 and selling as they fell, and also investing in floating-rate
                 bonds whose income rose as the Federal Reserve Board (the Fed)
                 raised rates.

                 The biggest driver of our outperformance, however, was
                 security selection. This USAA IMCO portion was overweight in
                 corporate bonds, with a focus on individual issues in finance,
                 utilities, and real estate investment trusts. We also
                 benefited from our decision to emphasize commercial
                 mortgage-backed securities over residential mortgages. Credit
                 for our ability to pick the right bonds in the right sectors
                 goes largely to USAA IMCO's team of 17 analysts here in San
                 Antonio.

                 With the economy in the sensitive transition period from high
                 to moderate growth, and with the Fed under new leadership,
                 we're avoiding making any big bets on duration as we move into
                 the new reporting year. Instead, we are continuing to focus on
                 what we do best, which is to use our research advantage to
                 find individual securities that we believe give us the most
                 value for a given level of risk.

HOW DID THE USAA IMCO-MANAGED PRECIOUS METALS AND MINERALS PORTION OF
THE FUND PERFORM?

                 The Fund's allocation to precious metals and minerals
                 securities helped performance, because the price of gold and
                 other commodities rose dramatically.

                 On behalf of everyone at USAA IMCO, Wellington, MFS, and
                 Batterymarch, we thank you for your investment in the Fund.

                         OVERVIEW

                 The graph on page 13 illustrates the comparison of a $10,000
                 hypothetical investment in the USAA Cornerstone Strategy Fund
                 to the following benchmarks:

                 o  The S&P 500 Index is an unmanaged index representing the
                    weighted average performance of a group of 500 widely held,
                    publicly traded stocks. It is not possible to invest
                    directly in the S&P 500 Index.

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

                        Public ACCOUNTING Firm

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF USAA CORNERSTONE STRATEGY FUND:

We have audited the accompanying statement of assets and liabilities of the USAA
Cornerstone Strategy 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 Cornerstone Strategy 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.

         (c) Variable-rate or floating-rate security - interest rate is
             adjusted periodically. The interest rate disclosed represents the
             current rate at May 31, 2006.

         (d) Interest-only commercial mortgage-backed securities (IO CMBSs) -
             represent the right to receive only the interest payments on an
             underlying pool of commercial mortgage loans. The interest rate
             disclosed is the purchase yield, which reflects an anticipated
             yield based upon interest rates at the time of purchase and the
             estimated timing and amount of future cash flows. The principal
             amount represents the notional amount of the underlying pool on
             which current interest is calculated. IO CMBSs are backed by loans
             that have various forms of prepayment protection, which include
             lock-out provisions, yield maintenance provisions, and prepayment
             penalties. This serves to moderate their prepayment risk. IO CMBSs
             are subject to recessionary default-related prepayments that may
             have a negative impact on yield.

         (e) Security has a mandatory call or put, which shortens its effective
             maturity date.

         (f) Eurodollar and Yankee obligations are dollar-denominated
             instruments that are issued outside the U.S. capital markets by
             foreign corporations and financial institutions and by foreign
             branches of U.S. corporations and financial institutions
             (Eurodollar obligations) as well as dollar-denominated instruments
             that are issued by foreign issuers in the U.S. capital markets
             (Yankee obligations).

         (g) The security or a portion thereof was out on loan as of May 31,
             2006.

         (h) Rate represents the money market fund annualized seven-day yield
             at May 31, 2006.

         (i) Collateral on repurchase agreements is received by the Fund upon
             entering into the repurchase agreement. The collateral is


                                                                              57

             marked-to-market daily to ensure its market value is equal to or
             in excess of the repurchase agreement price plus accrued interest.

         (j) U.S. government agency issues - mortgage-backed securities issued
             by Government National Mortgage Association (GNMA) and certain
             other U.S. government agencies 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.

         (k) Zero-coupon security. Rate represents the effective yield at date
             of purchase.

         (l) Callable security expected to be called prior to maturity due to a
             scheduled change from a fixed to a floating interest rate, which
             is likely to be uneconomical to the issuer.

         (m) Put bond - provides the right to sell the bond at face value at
             specific tender dates prior to final maturity. The put feature may
             shorten the effective maturity of the security.

         (n) Security deemed illiquid by the Manager, under liquidity
             guidelines approved by the Board of Trustees. The aggregate market
             value of these securities at May 31, 2006, was $511,000, which
             represented 0.03% of the Fund's net assets.

         (o) Variable-rate demand notes (VRDNs) - provide the right to sell the
             security at face value on either that day or within the rate-reset
             period. The interest rate is adjusted at a stipulated daily,
             weekly, monthly, quarterly, or other specified time interval to a
             rate that reflects current market conditions. VRDNs will normally
             trade as if the maturity is the earlier put date, even though
             stated maturity is longer.

         (p) Security was fair valued at May 31, 2006, by the Manager in
             accordance with valuation procedures approved by the Board of
             Trustees.

         (q) Represents less than 0.1% of net assets.

         (r) Stepped coupon security that is initially issued in zero-coupon
             form and converts to coupon form at the specified date and rate
             shown in the security's description. The rate presented in the

USAA CORNERSTONE STRATEGY 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 Cornerstone Strategy Fund
         (the Fund), which is classified as diversified under the 1940 Act. The
         Fund's investment objective is to achieve a positive, inflation-
         adjusted rate of return and a reasonably stable value of Fund shares,
         thereby preserving the purchasing power of shareholders' capital.

           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 closing 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,


                                                                              63

USAA CORNERSTONE STRATEGY FUND
MAY 31, 2006

                 events affecting the values of foreign securities that occur
                 between the time of their last quoted sales or official
                 closing 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 subadvisers, 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. Other 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

           (continued)

USAA CORNERSTONE STRATEGY FUND
MAY 31, 2006

                 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.

              7. 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
                 subadvisers, 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.


                                                                              65

           (continued)

USAA CORNERSTONE STRATEGY FUND
MAY 31, 2006

           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 are
              amortized over the life of the respective securities, using the
              effective yield method for long-term securities and the
              straight-line method for short-term securities.

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

USAA CORNERSTONE STRATEGY FUND
MAY 31, 2006

              1. Purchases and sales of securities, income, and expenses at the
                 exchange rate 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 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. 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


                                                                              67

              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, there were no outstanding delayed-delivery commitments
              or when-issued securities.

           G. 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 $121,000 and $27,000, respectively,
              resulting in a total reduction in Fund expenses of $148,000.

           H. 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.

           I. 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
         $3,000, which represents 5.0% 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.


                                                                              69

USAA CORNERSTONE STRATEGY FUND
MAY 31, 2006

         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
         $7,596,000, increase accumulated undistributed net investment income
         by $2,429,000, and decrease accumulated net realized gain on
         investments by $10,025,000. This includes differences in the
         accounting for foreign currency gains and losses, security paydowns,
         and passive foreign investment corporation 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*                        $ 16,721,000    $38,916,000
         Long-term realized capital gains         117,428,000     51,491,000


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

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

         Undistributed ordinary income                              $ 34,552,000
         Undistributed long-term capital gains                        75,982,000
         Unrealized appreciation of investments                      123,421,000
         Unrealized appreciation on foreign currency translations         46,000


         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
         deferral of gains 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/maturities of securities,
         excluding short-term securities, for the year ended May 31, 2006, were
         $2,445,413,000 and $2,382,783,000, respectively.

         As of May 31, 2006, the cost of securities, including short-term
         securities, for federal income tax purposes, was $1,763,960,000.

         Gross unrealized appreciation and depreciation of investments as of
         May 31, 2006, for federal income tax purposes, were $166,024,000 and
         $42,603,000, respectively, resulting in net unrealized appreciation of
         $123,421,000.

(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.


                                                                              71

(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. For the year
         ended May 31, 2006, the Fund received securities-lending income of
         $955,000, 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 $182,039,000, which excluded $751,000 of securities on
         loan that were sold prior to May 31, 2006. The Fund received cash
         collateral of $189,324,000 for the loans. Of this amount, $189,301,000
         was invested in short-term investments, as noted in the Fund's
         portfolio of investments, and $23,000 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 and for directly managing the
           day-to-day investment of a portion of the Fund's assets, subject to
           the authority of and supervision by the Trust's Board of Trustees.
           The Manager is also authorized to select (with approval of the
           Trust's Board of Trustees) one or more subadvisers to manage the
           day-to-day investment of a portion 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 Flexible Funds Index, which tracks
           the total return performance of the 10 largest funds in the Lipper
           Global Flexible Portfolio 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.


                                                                              73

           (continued)

USAA CORNERSTONE STRATEGY FUND
MAY 31, 2006

           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 Flexible 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 $11,903,000, which is net
           of a performance adjustment of $(412,000) that decreased the base
           management fee of 0.75% by 0.03%.

        B. SUBADVISORY ARRANGEMENTS - The Manager has entered into investment
           subadvisory agreements with Wellington Management Company, LLP
           (Wellington Management), MFS Investment Management (MFSIM), and
           effective December 1, 2005, with Batterymarch Financial Management,
           Inc.  (Batterymarch), under which Wellington Management directs the
           investment and reinvestment of a portion of the Fund's assets

           invested in U.S. stocks (as allocated from time to time by the
           Manager), MFSIM directs the investment and reinvestment of a portion
           of the Fund's assets invested in international stocks (as allocated
           from time to time by the Manager), and Batterymarch directs the
           investment and reinvestment of a portion of the Fund's assets
           invested in U.S. and international stocks (as allocated from time to
           time by the Manager). Prior to March 1, 2006, Wellington Management
           also directed the investment and reinvestment of the portion of the
           Fund's assets invested in real estate securities.

           Effective March 1, 2006, the Manager (not the Fund) pays Wellington
           Management a subadvisory fee in the annual amount of 0.20% of the
           portion of the Fund's average net assets that Wellington Management
           manages. Wellington Management has agreed to waive all fees in excess
           of 0.18% of the portion of the Fund's average net assets that
           Wellington Management manages through June 30, 2006. Wellington
           Management may terminate this waiver if the Manager allocates less
           than 100% of certain USAA funds' assets investable in U.S. stocks to
           Wellington Management. The Manager has allocated less than 100% of
           these funds' assets investable in U.S. stocks to Wellington
           Management, so Wellington Management may terminate this waiver at
           any time. Prior to March 1, 2006, the Manager (not the Fund) paid
           Wellington Management a subadvisory fee in the annual amount of
           0.40% of the first $50 million of the portion of the Fund's average
           net assets that Wellington Management managed and invested in real
           estate securities, plus 0.35% of the portion of the Fund's average
           net assets over $50 million that Wellington Management managed and
           invested in real estate securities, plus 0.20% of the portion of the
           Fund's average net assets that Wellington Management managed and
           invested in securities other than real estate securities. For the
           year ended May 31, 2006, the Manager incurred subadvisory fees, paid
           or payable to Wellington Management, of $1,092,000.


                                                                              75

           subadvisory fee in the annual amount of 0.29% of the portion 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

           assets over $250 million and up to $500 million, and 0.17% on assets
           over $500 million. For the year ended May 31, 2006, the Manager
           incurred subadvisory fees, paid or payable to Batterymarch, of
           $303,000.

           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

           incurred by the Manager. For the year ended May 31, 2006, the Fund
           reimbursed the Manager $52,000 for these legal and tax services.
           These expenses are included in the professional fees expenses on the
           Fund's statement of operations.

        D. EXPENSE LIMITATION - The Manager has voluntarily agreed to limit the
           annual expenses of the Fund to 1.19% of the Fund's average annual
           net assets, before reductions of any expenses paid indirectly, and
           will reimburse the Fund for all expenses in excess of that amount.

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

         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.

          average account value over the period, multiplied by 182 days/365
          days (to reflect the one-half year period). The Fund's ending account
          value on the first line in the table is based on its actual total
          return of 3.96% for the six-month period of December 1, 2005, through
          May 31, 2006.

SEPTEMBER BOARD MEETING
- --------------------------------------------------------------------------------

         As disclosed in the Information Statement to shareholders dated
         December 1, 2005, the Board of Trustees, including the Trustees who
         are not "interested persons" of the Trust (the "Independent
         Trustees"), at a meeting held on September 14, 2005, approved the
         adoption of an Investment Subadvisory Agreement with Batterymarch
         Financial Management, Inc. (Batterymarch). In advance of the meeting,
         the Board received and considered a variety of information relating to
         the Investment Subadvisory Agreement and Batterymarch, 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) materials about Batterymarch's new "best ideas"
         global investment strategy; (ii) the qualifications of the individuals
         at Batterymarch responsible for these investment activities; (iii) the
         fees to be paid to Batterymarch; and (iv) the complementary nature of
         the investment strategies of Batterymarch with the existing
         subadvisers Wellington Management Company, LLP and MFS Investment
         Management. Prior to voting, the Independent Trustees reviewed the
         proposed Investment 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 Investment Subadvisory Agreement. The Independent Trustees
         also reviewed the proposed Investment Subadvisory Agreement in private
         sessions with their counsel at which no representatives of management
         were present.

         In approving the Fund's Investment Subadvisory Agreement with
         Batterymarch, the Board considered various factors, among them: (i)
         the nature, extent, and quality of services to be provided to the Fund
         by Batterymarch, including the personnel that will be providing
         services; (ii) Batterymarch's compensation and any other benefits that
         will be derived from the subadvisory relationship by Batterymarch;
         (iii) comparisons, to the extent available, of subadvisory fees and

         performance to comparable investment companies; and (iv) the terms of
         the Investment Subadvisory Agreement. The Board's analysis of these
         factors is set forth below.

         After full consideration of a variety of factors, the Board, including
         the Independent Trustees, voted to approve the Investment Subadvisory
         Agreement with Batterymarch. In approving the Investment Subadvisory
         Agreement, the Board did not identify any single factor as
         controlling, and each Independent Board Member 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 Board considered information provided to them
         regarding the services to be provided by Batterymarch. The Board
         considered Batterymarch's level of knowledge and investment style. The
         Board reviewed the experience and credentials of the investment
         personnel who will be responsible for managing the investment of
         portfolio securities with respect to the Fund and Batterymarch's level
         of staffing. The Board 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 Board also noted
         Batterymarch's brokerage practices. The Board also considered
         Batterymarch's regulatory and compliance history. The Board noted that
         the Manager's monitoring processes of Batterymarch will 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
         Batterymarch.

         SUBADVISER COMPENSATION. The Board also took into consideration the
         financial condition of Batterymarch. In considering the cost of
         services to be provided by Batterymarch and the profitability to
         Batterymarch


                                                                              83

         of its relationship with the Fund, the Board noted that the fees under
         the Investment Subadvisory Agreement will be paid by the Manager. The
         Board also relied on the ability of the Manager to negotiate the
         Investment 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 Batterymarch, Batterymarch's anticipated
         profitability with respect to the Fund, and the potential economies of
         scale in Batterymarch's management of the Fund, to the extent
         available. However, this information was less significant to the
         Board's consideration of the Investment Subadvisory Agreement than the
         other factors considered.

         SUBADVISORY FEES AND FUND PERFORMANCE. The Board noted that the "best
         ideas" global investment strategy is a new product offering from
         Batterymarch; and as a result, the Board received no information about
         the fees that Batterymarch charges to comparable clients. The Board
         considered that the Fund pays a management fee to the Manager and
         that, in turn, the Manager will pay a subadvisory fee to Batterymarch.
         The Board noted the Manager's expertise and resources in monitoring
         the performance, investment style, and risk-adjusted performance of
         Batterymarch. The Board also noted Batterymarch's long-term
         performance record for other accounts.

         CONCLUSION. The Board reached the following conclusions regarding the
         Investment Subadvisory Agreement, among others: (i) Batterymarch is
         qualified to manage a portion of the Fund's assets in accordance with
         its investment objectives and policies; (ii) Batterymarch maintains an
         appropriate compliance program; (iii) Batterymarch's performance in
         managing other accounts is reasonable; 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 Batterymarch. Based on
         its conclusions, the Board determined that approval of the Investment
         Subadvisory Agreement with Batterymarch would be in the interests of
         the Fund and its shareholders.

APRIL BOARD MEETING
- --------------------------------------------------------------------------------

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


                                                                              85

         things, information concerning the Fund's performance and related
         services provided by the Manager and by each Subadviser. At the
         meeting at which the renewal of the Investment Advisory Agreement and
         Subadvisory Agreements 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 Subadvisers is
         an ongoing one. In this regard, the Board's and its committees'
         consideration of the Investment Advisory Agreement and Subadvisory
         Agreements included certain information previously received at such
         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.

         The Board considered the Manager's management style and the
         performance of its duties under the Investment Advisory Agreement. The
         Board considered the level and depth of knowledge of the Manager,
         including the professional experience and qualifications of its senior
         and investment personnel, as well as current staffing levels. The
         Board discussed the Manager's effectiveness in monitoring the
         performance of the Subadvisers and its timeliness in responding to
         performance issues. The allocation of the Fund's brokerage, including
         the Manager's process for monitoring "best execution" and the
         utilization of "soft dollars," were 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


                                                                              87

         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
         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 fee adjustment as well as any fee waivers or
         reimbursements - was above the median of its expense group and below
         the median of its expense universe. The data indicated that the Fund's
         total expenses, after reimbursements, were lower than 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 any performance adjustment to
         such fee. The Trustees also took into account the Manager's current
         voluntary undertakings to maintain expense limitations for the Fund
         and that the subadvisory fees under the Subadvisory Agreements 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 lower than the average of its performance universe and its Lipper
         index for the one- and three-year periods ended December 31, 2005, and
         was lower than the average of its performance universe and exceeded
         the average of its Lipper index 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
         Trustees considered the Manager's discussion of the factors
         contributing to the Fund's underperformance and its plan 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


                                                                              89

         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 discussions 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 party. The Board also considered the fee
         waivers and expense reimbursement arrangements by the Manager and the
         fact that the Manager pays the subadvisory fees. The Board also took
         into account other economies of scale achieved by the Fund with
         respect to certain fixed expenses as a result of the Fund's asset
         size. 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 its conclusions,
         the Board determined that continuation of the Investment Advisory
         Agreement would be in the interests of the Fund and its shareholders.

SUBADVISORY AGREEMENTS
- --------------------------------------------------------------------------------

         In approving each Subadvisory Agreement with respect to the Fund, the
         Board considered various factors, among them: (i) the nature, extent,


90

 A D V I S O R Y
================----------------------------------------------------------------
                 AGREEMENTS (unaudited)
                 (continued)

         and quality of services provided to the Fund by the respective
         Subadviser, 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 each
         Subadvisory Agreement. In approving each 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 Subadvisers, including
         information presented periodically throughout the previous year. The
         Board considered each 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 each Subadviser's
         level of staffing. The Trustees noted that the materials provided to
         them by each Subadviser 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 each Subadviser's brokerage practices. The
         Board also considered each Subadviser's regulatory and compliance
         history. The Board noted that the Manager's monitoring processes of
         each 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.


                                                                              91

         SUBADVISER COMPENSATION. The Board also took into consideration the
         financial condition of each Subadviser. In considering the cost of
         services to be provided by each Subadviser and the profitability to
         that 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 each 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 each Subadviser,
         each Subadviser's profitability with respect to the Fund, and the
         potential economies of scale in each 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 Agreements than the other factors considered.

         SUBADVISORY FEES AND FUND PERFORMANCE. The Board compared the
         subadvisory fees for the Fund with the fees that each 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 each 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 also considered the performance of each
         Subadviser. The Board noted the Manager's expertise and resources in
         monitoring the performance, investment style, and risk-adjusted
         performance of each Subadviser. The Board was mindful of the Manager's
         focus on each Subadviser's performance and the explanations of
         management regarding the factors that contributed to the recent
         performance of the Fund. The Board also noted each Subadviser's
         long-term performance record for similar accounts.

         CONCLUSION. The Board reached the following conclusions regarding each
         Subadvisory Agreement, among others: (i) each Subadviser is qualified
         to manage the Fund's assets in accordance with its investment
         objectives and policies; (ii) each 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 each Subadviser. Based on the Board's conclusions,
         the Board of Trustees determined that approval of each 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.

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.

have a fiscal  year-end  of May 31 and are  included  within  this  report  (the
Funds). The aggregate fees billed by the Registrant's independent auditor, Ernst
& Young LLP,  for  professional  services  rendered  for the audit of the Funds'

by USAA Shareholder  Account Services (SAS) for professional  services  rendered
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:

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


(d) ALL OTHER  FEES.  No such fees were  billed by Ernst & Young LLP for  fiscal
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
were not required to be pre-approved by the Registrant's Audit Committee because
the services were not directly  related to the  operations  of the  Registrant's
funds.  The  Board  of  Directors/Trustees  will  consider  Ernst & Young  LLP's
independence and will consider whether the provision of these non-audit services
to IMCO is compatible with maintaining Ernst & Young LLP's independence.

ITEM 10.  CONTROLS AND PROCEDURES

The  principal  executive  officer  and  principal  financial  officer  of  USAA
Investment Trust (Trust) have concluded that the Trust's disclosure controls and
procedures are sufficient to ensure that information required to be disclosed by
the Trust in this Form N-CSR was recorded,  processed,  summarized  and reported

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.
