PRESIDENT'S MESSAGE

"LOOKING BACK AT THE MARKET DECLINE,
MANY INVESTORS WERE NOT APPROPRIATELY [PHOTO OF DANIEL S. McNAMARA]
POSITIONED RELATIVE TO THEIR RISK
TOLERANCE."

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

JANUARY 2010

Equities had a remarkable run during 2009. Between March 9, 2009, when the
market reached a bottom and the end of the year, stock prices steadily climbed.
Although the rally did not completely erase the declines of 2008, the market has
established a beachhead and is moving in the right direction. Likewise, the
worst of the Great Recession appears to be over. After three quarters of
negative growth, the gross domestic product (GDP) -- the broadest measure of
U.S. economic activity -- rose by 2.2% in the third quarter of 2009. Other
important measures of economic activity have also trended higher, including
industrial production, retail sales, and residential real estate sales.

Will the recovery be swift? Or will there be a "double dip?" I say "no" to both
questions. Significant assets -- including vast amounts of U.S. government
stimulus -- have been thrown into the breach. As a result, I don't expect the
economy to fall back into a recession. But I don't expect a quick recovery
either. Instead, I anticipate a slow and steady slog with lower economic growth
than the United States has enjoyed in recent decades. Access to credit is likely
to remain tight until the securitization markets heal and banks relax lending
standards. Most consumers and businesses will continue rebuilding their balance
sheets by increasing their savings rate and reducing their spending and
borrowing. While the outlook for job growth has improved, unemployment is likely
to persist at an uncomfortably high level for most of 2010.

================================================================================

2 | USAA S&P 500 INDEX FUND
<PAGE>

================================================================================

I also think the equity market is expecting a strong cyclical recovery.
Although many stocks seemed to trade at appropriate levels at the end of 2009,
we see support for some growth in prices over the near term. Meanwhile,
consensus forecasts (which are based on individual company estimates) call for
corporate earnings growth of 30% or more during 2010. Meeting these expectations
will require significant top-line revenue growth, not just more cost cutting.
USAA's expectations are more in line with top-down earnings forecasts in the 8%
to 15% range.

Of course, no one really knows what will happen. That's why it is important to
revisit your investment plan. A new year is an opportune time to stop and take
stock. Looking back at the market decline, many investors were not appropriately
positioned relative to their risk tolerance. With this in mind, I have
undertaken a review of my own investment portfolio. The process gives me the
opportunity to reflect on my goals, re-evaluate my risk tolerance, consider
changes in my investment strategy, and reposition my portfolio accordingly. I
urge you to do the same. Our trained service representatives are standing ready
to assist you -- free of charge.

At USAA Investment Management Company, we appreciate the trust you have placed
in us. We will continue to offer what we consider an excellent value -- some of
the industry's top investment talent, first-class service, and no-load mutual
funds. Thank you for the opportunity to help you with your investment needs.

Sincerely,

/S/ DANIEL S. MCNAMARA

MANAGER'S COMMENTARY ON THE FUND

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

o HOW DID THE USAA S&P 500 INDEX FUND (THE FUND) PERFORM DURING 2009?

 The Fund closely tracked its benchmark, the S&P 500(R) Index (the Index),
 for the year ended December 31, 2009. The Fund produced a return of 26.28%
 (Member Shares) and 26.47% (Reward Shares) for the period, as compared to
 26.46% for the benchmark. The broad-based index is a group of large-company
 stocks that is not available for direct investment.

 Though recovering from a negative year in 2008, large-cap stocks
 underperformed both mid-cap stocks and small-caps stocks in 2009. Mid-cap
 stocks, as represented by the S&P 400(R) MidCap Index, returned 37.38% for
 the period and small-cap stocks, as represented by the Russell 2000(R)
 Index, returned 27.17%.

o WHAT WERE MARKET CONDITIONS DURING THE PERIOD?

 The beginning of the first quarter in 2009 continued to be marked by
 extreme volatility in equity markets around the world as grim economic news
 persisted, including the announcement that the United States officially
 slid into a recession. Increasing unemployment, decreases in manufacturing,
 and continued weakness in consumer spending plagued the first quarter. In
 the face of a rapidly crumbling economy, President Barack Obama's new
 administration passed a $787 billion stimulus plan on February 17, 2009.

================================================================================

================================================================================

 hit a low for the year on March 9, 2009. International markets staged a
 rally in late March 2009 when U.S. Treasury Secretary Timothy Geithner
 provided additional details on the government's plan to relieve banks of
 their toxic assets and improve the flow of credit.

 The stock market rally that began in March 2009 displayed no signs of a
 slowdown during the third quarter of the year. By the end of September
 2009, the Index had climbed 58.25% from its low on March 9, 2009. This
 recovery was supported in part by an improvement in economic data such as
 second-quarter GDP growth numbers that came in at a revised -0.7%, a
 substantial improvement from the first quarter GDP results. Third-quarter
 market performance also was boosted by a number of corporate earnings
 reports that beat expectations.

 The fourth quarter began on a weak note following substandard macroeconomic
 data and questions about the quality of company earnings. The indexes
 improved in November and December, benefiting from stronger macroeconomic
 data and earnings announcements and as more banks repaid their Troubled
 Asset Relief Program (also known as "TARP") loans in full following large
 equity offerings. Positive news in December included an unexpected increase
 in U.S. pending home sales, the Federal Reserve Board pledged to keep rates
 low, and a report of better-than-expected sales forecast from auto makers.

o PLEASE DESCRIBE SECTOR PERFORMANCE.

 All sectors posted positive returns for the year ending 2009. The largest
 gain was seen in Information Technology, which returned 61.72% for the
 year. Information Technology is the largest sector in the Index
 representing 19.86%. Other strong performers were Consumer Discretionary
 and Industrials which posted returns of 41.30% and 20.93% respectively.
 Financials, with a weight of 14.38% of the Index returned 17.22% for the
 year.

<PAGE>

================================================================================

o WHAT INVESTMENT STRATEGIES WILL YOU PURSUE FOR THE FUND IN 2010?

 We don't manage the Fund according to a given outlook for the equity
 markets or the economy in general, because we're managing an index fund
 that seeks to replicate as closely as possible (before deduction of
 expenses) the broad diversification and returns of the Index. Nevertheless,
 we will monitor economic conditions and their effect on the financial
 markets as we seek to track closely the index's performance.

 Thank you for your investment in the Fund.

 LIPPER LEADERS (OVERALL)
 REWARD SHARES

 [5] [5] [5]
 TOTAL RETURN PRESERVATION EXPENSE

The Fund's Reward Shares are listed as a Lipper Leader for Total Return and
Expense among 164 and 49 funds, respectively, within the Lipper S&P 500 Index
Funds category, and for Preservation among 9,246 equity funds, for the overall
period ended December 31, 2009. The Fund's Reward Shares received a Lipper
Leader rating for Total Return among 164 and 148 funds for the three- and
five-year periods, respectively, a Lipper Leader rating for Preservation among
7,392 funds for the five-year period and a score of 4 among 9,246 funds for the
three-year period within the Lipper S&P 500 Index Funds category. The Fund's
Reward shares received a Lipper Leader rating for Expense among 49 and 41 equity
funds for the three- and five-year periods, respectively. Lipper ratings for
Total Return reflect funds' historical total return performance relative to
peers as of December 31, 2009. Lipper ratings for Preservation reflect funds'
historical loss avoidance relative to other funds within the same asset class as
of December 31, 2009. Preservation ratings are relative, rather than absolute,
measures, and funds named Lipper Leaders for Preservation may still experience
losses periodically; those losses may be larger for equity and mixed equity
funds than for fixed-income funds. Lipper ratings for Expense reflect funds'
expense minimization relative to peers with similar load structures as of
December 31, 2009.

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

Ratings are subject to change every month and are based on an equal-weighted
average of percentile ranks for the Total Return, Preservation, and Expense
metrics over three-, five-, and 10-year periods (if applicable). The highest 20%
of funds in each peer group are named Lipper Leaders, the next 20% receive a
score of 4, the middle 20% are scored 3, the next 20% are scored 2, and the
lowest 20% are scored 1. Lipper ratings are not intended to predict future
results, and Lipper does not guarantee the accuracy of this information. More

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF USAA S&P 500 INDEX FUND:

We have audited the accompanying statements of assets and liabilities, including
the portfolio of investments, of the USAA S&P 500 Index Fund (one of the
portfolios constituting USAA Mutual Funds Trust) (the "Fund") as of December 31,
2009, 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 five 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
audits.

We conducted our audits 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 misstatements. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits 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 December 31, 2009, by correspondence with the custodian
and brokers or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide 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 S&P 500 Index Fund at December 31, 2009, 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 five years
in the period then ended, in conformity with U.S. generally accepted accounting
principles.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USAA MUTUAL FUNDS 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 Delaware statutory trust consisting of 46 separate funds. The
information presented in this annual report pertains only to the USAA S&P 500
Index Fund (the Fund), which is classified as diversified under the 1940 Act.
The Fund seeks to match, before fees and expenses, the performance of the S&P
500 Index. USAA Investment Management Company (the Manager), an affiliate of the
Fund, has retained Northern Trust Investments, N.A. (NTI) to serve as subadviser
for the Fund. NTI is responsible for investing the Fund's assets. Under normal
market conditions, NTI attempts to achieve the Fund's objective by investing at
least 80% of the Fund's assets in the stocks of companies composing the S&P 500
Index.

The Fund has two classes of shares: Member Shares and Reward Shares. Each class
of shares has equal rights to assets and earnings, except that each class bears
certain class-related expenses specific to the particular class. These expenses
include administration and servicing fees, transfer agency fees, postage,
shareholder reporting fees, and certain registration and custodian fees.
Expenses not attributable to a specific class, income, and realized gains or
losses on investments are allocated to each class of shares based on each
class's relative net assets. Each class has exclusive voting rights on matters
related solely to that class and separate voting rights on matters that relate
to both classes. The Reward Shares are offered for sale to qualified public
shareholders and to the USAA Target Retirement Funds (Target Funds), which are
managed by the Manager.

================================================================================

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 NYSE 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. If no last sale or official closing price is reported or
 available, the average of the bid and asked prices generally is used.

 2. Investments in open-end investment companies, hedge, or other funds,
 other than ETFs, are valued at their net asset value (NAV) at the end
 of each business day.

 3. Debt securities purchased with original or remaining maturities of 60
 days or less may be valued at amortized cost, which approximates market
 value.

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

 5. Futures are valued based upon the last sale price at the close of
 market on the principal exchange on which they are traded.

 6. Securities for which market quotations are not readily available or are
 considered unreliable, or whose values have been materially affected by
 events occurring after the close of their primary markets but before
 the pricing of the Fund, are valued in good faith at fair value, using
 methods determined by the Manager in consultation with the Fund's
 subadviser, if applicable, under valuation procedures approved by the
 Trust's Board of Trustees. The effect of fair value pricing is that
 securities may not be priced on the basis of quotations from the
 primary market in which they are traded and the actual price realized
 from the sale of a security may differ materially from the fair value
 price. Valuing these

================================================================================

44 | USAA S&P 500 INDEX FUND
<PAGE>

================================================================================

 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. FAIR VALUE MEASUREMENTS -- Fair value is defined as the price that would be
 received to sell an asset or paid to transfer a liability in an orderly
 transaction between market participants at the measurement date. The
 three-level valuation hierarchy disclosed in the portfolio of investments
 is based upon the transparency of inputs to the valuation of an asset or
 liability as of the measurement date. The three levels are defined as
 follows:

 Level 1 -- inputs to the valuation methodology are quoted prices
 (unadjusted) in active markets for identical securities.

 Level 2 -- inputs to the valuation methodology are other significant
 observable inputs, including quoted prices for similar securities, inputs
 that are observable for the securities, either directly or indirectly, and
 market-corroborated inputs such as market indices.

 Level 3 -- inputs to the valuation methodology are unobservable and
 significant to the fair value measurement, including the Manager's own
 assumptions in determining the fair value.

 The inputs or methodologies used for valuing securities are not necessarily
 an indication of the risks associated with investing in those securities.

C. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES -- On January 1, 2009, the
 Fund adopted an accounting standard that requires

================================================================================




 NOTES TO FINANCIAL STATEMENTS | 45
<PAGE>

================================================================================

 qualitative disclosures about objectives and strategies for using
 derivatives, quantitative disclosures about fair value amounts of and gains
 and losses on derivative instruments, and disclosures about
 credit-risk-related contingent features in derivative agreements, if any.

 The Fund may buy, sell, and enter into certain types of derivatives,
 including, but not limited to futures contracts and options on futures
 contracts under circumstances in which such instruments are expected by the
 portfolio manager to aid in achieving the Fund's investment objective. The
 Fund also may use derivatives in circumstances where the portfolio manager
 believes they offer an economical means of gaining exposure to a particular
 securities market, or to keep cash on hand to meet shareholder redemptions
 or other needs while maintaining exposure to the market. With exchange
 listed futures contracts and options, counterparty credit risk to the Fund
 is limited to the exchange's clearinghouse which, as counterparty to all
 exchange traded futures contracts and options, guarantees the transactions
 against default from the actual counterparty to the trade.

 FUTURES CONTRACTS -- The Fund is subject to cash flow and tracking error
 risk in the normal course of pursuing its investment objectives. The Fund
 may use stock index futures contracts in an attempt to reduce any
 performance discrepancies between the Fund and the S&P 500 Index. A futures
 contract represents a commitment for the future purchase or sale of an
 asset at a specified price on a specified date. Upon entering into such
 contracts, the Fund is required to deposit with the broker in either cash
 or securities an initial margin in an amount equal to a certain percentage
 of the contract amount. Subsequent payments (variation margin) are made or
 received by the Fund each day, depending on the daily fluctuations in the
 value of the contract, and are recorded for financial statement purposes as
 unrealized gains or losses. When the contract is closed, the Fund records a
 realized gain or loss equal to the difference between the value of the
 contract at the time it was opened and the value at the time it was closed.
 Upon entering into such contracts, the Fund bears the risk of interest

 or exchange rates or securities prices moving unexpectedly in an unfavorable
 direction, in which case, the Fund may not achieve the anticipated benefits
 of the futures contracts.

D. REPURCHASE AGREEMENTS -- The Fund may enter into repurchase agreements with
 commercial banks or recognized security dealers.

================================================================================



 NOTES TO FINANCIAL STATEMENTS | 47
<PAGE>

================================================================================

 These agreements are collateralized by underlying securities. The
 collateral obligations are marked-to-market daily to ensure their value is
 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. Repurchase agreements are subject to credit risk, and the Fund's
 Manager monitors the creditworthiness of sellers with which the Fund may
 enter into repurchase agreements.

E. 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.

F. 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 daily on the accrual basis. Discounts and premiums on short-term
 securities are amortized on a straight-line basis over the life of the
 respective securities.

G. EXPENSES PAID INDIRECTLY -- Through arrangements with banks utilized by the
 Fund for cash management purposes, realized credits, if any, generated from
 cash balances in the Fund's bank accounts may be used to directly reduce
 the Fund's expenses. For the year ended December 31, 2009, these bank
 credits reduced the expenses of the Member Shares and Reward Shares by less
 than $500.

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

================================================================================

48 | USAA S&P 500 INDEX FUND
<PAGE>

================================================================================

 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 $750 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 0.13% annually of the amount of the committed loan
agreement). Prior to September 25, 2009, the maximum annual facility fee was
0.07% of the amount of the committed loan agreement. The facility fees are
allocated among the funds based on their respective average net assets for the
period.

For the year ended December 31, 2009, the Fund paid CAPCO facility fees of
$13,000, which represents 6.0% of the total fees paid to CAPCO by the USAA
funds. The Fund had no borrowings under this agreement during the year ended
December 31, 2009.

================================================================================

(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.

The tax character of distributions paid during the years ended December 31,
2009, and 2008, was as follows:

 2009 2008
 ------------------------------
Ordinary income* $49,872,000 $61,498,000

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

As of December 31, 2009, the components of net assets representing distributable
earnings on a tax basis were as follows:



Undistributed ordinary income $ 73,000
Accumulated capital and other losses (291,022,000)
Unrealized appreciation of investments 119,348,000


The difference between book-basis and tax-basis unrealized appreciation of
investments is attributable to the tax deferral of losses on wash sales.

Distributions of net investment income are made quarterly. Distributions of
realized gains from security transactions not offset by capital losses are made
annually in the succeeding fiscal year or as otherwise required to avoid the
payment of federal taxes. At December 31, 2009, the Fund had a current
post-October capital loss of $116,000 and capital loss carryovers of
$290,906,000, for federal income tax purposes. The post-October loss will be
recognized on the first day of the following fiscal year. If not offset by
subsequent capital gains, the capital loss carryovers will expire between 2010
and 2017, as shown on the next page. It is unlikely that the Trust's Board of
Trustees will authorize a distribution of capital gains realized in the future
until the capital loss carryovers have been used or expire.

 ============


The Fund is required to evaluate tax positions taken or expected to be taken in
the course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Income tax and related interest and penalties would be recognized by
the Fund as tax expense in the statement of operations if the tax positions were
deemed to not meet the more-likely-than-not threshold. For the year ended
December 31, 2009, the Fund did not incur any income tax, interest, or
penalties. As of December 31, 2009, the Manager has reviewed all open tax years
and concluded that there was no impact to the Fund's net assets or results of
operations. Tax years ended December 31, 2006, through December 31, 2009, remain
subject to examination by the Internal Revenue Service and state taxing
authorities. On an ongoing basis, the Manager will monitor its tax positions to
determine if adjustments to this conclusion are necessary.

(4) INVESTMENT TRANSACTIONS

Cost of purchases and proceeds from sales/maturities of securities, excluding
short-term securities, for the year ended December 31, 2009, were $182,035,000
and $113,789,000, respectively.

As of December 31, 2009, the cost of securities, including short-term
securities, for federal income tax purposes, was $2,612,109,000.

================================================================================




 NOTES TO FINANCIAL STATEMENTS | 51
<PAGE>

================================================================================

Gross unrealized appreciation and depreciation of investments as of December 31,
2009, for federal income tax purposes, were $667,099,000 and $547,751,000,
respectively, resulting in net unrealized appreciation of $119,348,000.

(5) LENDING OF PORTFOLIO SECURITIES

The Fund, through its third-party securities-lending agent, Wachovia Global
Securities Lending (Wachovia), 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. Cash
collateral requirements are determined daily based on the prior business day's
ending value of securities loaned. Imbalances in cash collateral may occur on
days where market volatility causes security prices to change significantly, and
are adjusted the next business day. The Fund and Wachovia 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 transaction.
Wachovia 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 Bank, N.A., parent company of Wachovia, has agreed to
indemnify the Fund against any losses due to counterparty default in
securities-lending transactions. For the year ended December 31, 2009, the Fund
received securities-lending income of $1,196,000, which is net of the 20% income
retained by Wachovia. As of December 31, 2009, the Fund loaned securities having
a fair market value of approximately $8,732,000 and received cash collateral of
$9,893,000 for the loans, which was invested in short-term investments, as noted
in the Fund's portfolio of investments.

(7) TRANSACTIONS WITH MANAGER

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

================================================================================




 NOTES TO FINANCIAL STATEMENTS | 53
<PAGE>

================================================================================

 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 Fund's management fees are accrued daily
 and paid monthly at an annualized rate of 0.10% of the Fund's average net
 assets for the fiscal year. For the year ended December 31, 2009, the Fund
 incurred management fees, paid or payable to the Manager, of $2,307,000.

B. SUBADVISORY ARRANGEMENTS -- The Manager has entered into an investment
 subadvisory agreement with NTI, under which NTI directs the investment and
 reinvestment of the Fund's assets (as allocated from time to time by the
 Manager). The Manager (not the Fund) pays NTI a subadvisory fee in an
 annual amount of 0.02% of the Fund's average daily net assets on amounts up
 to $1.5 billion; 0.01% of the Fund's average daily net assets for the next
 $1.5 billion; and 0.005% of the Fund's average daily net assets that exceed
 $3 billion. For the year ended December 31, 2009, the Manager incurred
 subadvisory fees, paid or payable to NTI, of $380,000.

 NTI has agreed to remit to the Fund all subadvisory fees earned on Fund
 assets invested in any of NTI's affiliated money market funds. For the
 year ended December 31, 2009, NTI remitted $2,000 to the Fund for the
 investments in the Northern Institutional Funds Money Market Portfolios.

 NTI is a direct subsidiary of The Northern Trust Company, the Fund's
 custodian and accounting agent.

C. ADMINISTRATION AND SERVICING FEES -- The Manager provides certain
 administration and shareholder servicing functions for the Fund. For such
 services, the Manager receives a fee accrued daily and paid monthly at an
 annualized rate of 0.06% of the Fund's average net assets for the fiscal
 year. For the year ended December 31, 2009, the Member Shares and Reward
 Shares incurred administration and servicing fees, paid or payable to the
 Manager, of $930,000 and $454,000, respectively.

 In addition to the services provided under its Administration and Servicing
 Agreement with the Fund, the Manager also provides

================================================================================

54 | USAA S&P 500 INDEX FUND
<PAGE>

================================================================================

 certain compliance and legal services for the benefit of the Fund. The
 Trust's Board of Trustees has approved the reimbursement of a portion of
 these expenses incurred by the Manager. For the year ended December 31,
 2009, the Fund reimbursed the Manager $93,000 for these compliance and
 legal services. These expenses are included in the professional fees on the
 Fund's statement of operations.

D. EXPENSE LIMITATION -- The Manager has voluntarily agreed to limit the
 annual expenses of the Member Shares and the Reward Shares to 0.25% and
 0.09%, respectively, of their annual average net assets, excluding
 extraordinary expenses and before reductions of any expenses paid
 indirectly, and will reimburse the Fund for all expenses in excess of those
 amounts. The Manager may modify or terminate this voluntary agreement at
 any time. For the year ended December 31, 2009, the Fund incurred
 reimbursable expenses from the Manager for the Member Shares and the Reward
 Shares of $2,353,000 and $1,092,000, respectively, of which $206,000 in
 total was receivable from the Manager.

 In addition, NTI has contractually agreed to reimburse the Fund for all
 license fees paid by the Fund to Standard & Poor's, in amounts not
 exceeding the annual rate of 0.001% of the average daily net assets of the
 Fund. For the year ended December 31, 2009, the Fund incurred reimbursable
 expenses from NTI for the Member Shares and the Reward Shares of $15,000
 and $8,000, respectively.

E. TRANSFER AGENT'S FEES -- USAA Transfer Agency Company, d/b/a USAA
 Shareholder Account Services (SAS), an affiliate of the Manager, provides
 transfer agent services to the Fund based on an annual charge of $20 per
 shareholder account plus out-of-pocket expenses. The Fund also pays SAS
 fees that are related to the administration and servicing of accounts that
 are traded on an omnibus basis. For the year ended December 31, 2009, the
 Fund incurred transfer agent's fees, paid or payable to SAS for the Member
 Shares and Reward Shares, of $3,267,000 and $438,000, respectively.

 distribution of the Fund's shares on a continuing best-efforts basis. The
 Manager receives no commissions or fees for this service.

G. ACCOUNT MAINTENANCE FEE -- SAS assesses a $10 annual account maintenance
 fee to allocate part of the fixed cost of maintaining shareholder accounts.
 This fee is charged directly to the shareholders' accounts and does not
 impact the Fund. The fee is waived on accounts with balances of $10,000 or
 more.

EXPENSE EXAMPLE

December 31, 2009 (unaudited)

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

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: direct costs, such
as account maintenance fees, 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 July 1, 2009, through
December 31, 2009.

ACTUAL EXPENSES

The line labeled "actual" under each share class in 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 for your share
class in the "actual" line under the heading "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

Actual expenses in the table on the next page do not reflect the effect of the
annual $10.00 account maintenance fee that is assessed on accounts with balances
of less than $10,000, at a rate of $2.50 per quarter. To include the effect of
this fee on the expenses that you paid, add $5.00 ($2.50 for two quarters) to
your calculated estimated expenses. If you are currently assessed this fee, your
ending account value reflects the quarterly deduction from your account.

================================================================================

 EXPENSE EXAMPLE | 59
<PAGE>

================================================================================

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The line labeled "hypothetical" under each share class in the table provides
information about hypothetical account values and hypothetical expenses based on
the Fund's actual expense ratios for each class 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 account
maintenance fees, 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.

Hypothetical
 (5% return before expenses) 1,000.00 1,024.75 0.46



* Expenses are equal to the Fund's annualized expense ratio of 0.25% for Member
 Shares and 0.09% for Reward Shares, which are net of any reimbursements and
 expenses paid indirectly, multiplied by the average account value over the
 period, multiplied by 184 days/365 days (to reflect the one-half-year period).
 The Fund's actual ending account values are based on its actual total returns
 of 22.47% for Member Shares and 22.56% for Reward Shares for the six-month
 period of July 1, 2009, through December 31, 2009.

ITEM 2. CODE OF ETHICS.

On September 24, 2009, the Board of Trustees of USAA Mutual Funds Trust approved
a Code of Ethics (Sarbanes Code) applicable solely to its senior financial
officers, including its principal executive officer (President), as defined
under the Sarbanes-Oxley Act of 2002 and implementing regulations of the
Securities and Exchange Commission. A copy of the Sarbanes Code is attached as
an Exhibit to this Form N-CSR.

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






ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

On November 18, 2008, the Board of Trustees of USAA Mutual Funds Trust
designated Dr. Barbara B. Ostdiek, Ph.D. as the Board's audit committee
financial expert. Dr. Ostdiek has served as an Associate Professor of Management
at Rice University since 2001. Dr. Ostdiek also has served as an Academic
Director at El Paso Corporation Finance Center since 2002. Dr. Ostdiek 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 Mutual Funds Trust.






ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a) AUDIT FEES. The Registrant, USAA Mutual Funds Trust, consists of 46 funds in
all. Only 10 funds of the Registrant have a fiscal year-end of December 31 and are
included within this report (the Funds). The aggregate fees accrued or billed by
the Registrant's independent auditor, Ernst & Young LLP, for professional
services rendered for the audit of the Registrant's annual financial statements
and services provided in connection with statutory and regulatory filings by the
Registrant for the Funds for fiscal years ended December 31, 2009 and 2008 were
$262,287 and $244,927, respectively.

(b) AUDIT RELATED FEE. The aggregate fees accrued or paid to Ernst & Young, LLP
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 December 31, 2009 and 2008 were $61,513
and $63,500, respectively. All services were preapproved by the Audit Committee.

(c) TAX FEES. No such fees were billed by Ernst & Young LLP for the review of
federal, state and city income and tax returns and excise tax calculations for
fiscal years ended December 31, 2009 and 2008.

(d) ALL OTHER FEES. No such fees were billed by Ernst & Young LLP for fiscal
years ended December 31, 2009 and 2008.

(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 December 31, 2009 and 2008 were $104,896 and
$108,000, respectively.

(h) Ernst & Young LLP provided non-audit services to IMCO in 2009 and 2008 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 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 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

Not Applicable.



ITEM 6. SCHEDULE OF INVESTMENTS.

Filed as part of the report to shareholders.






ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

Not Applicable.



ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

Not Applicable.



Item 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT
COMPANY AND AFFILIATED PURCHASERS.

Not Applicable.



ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

The Corporate Governance Committee selects and nominates candidates for
membership on the Board as independent directors. Currently, there is no
procedure for shareholders to recommend candidates to serve on the Board.






ITEM 11. CONTROLS AND PROCEDURES

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

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



ITEM 12. 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 FUNDS TRUST

I. PURPOSE OF THE CODE OF ETHICS

 USAA Mutual Funds Trust (the Trust or the Funds) has 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 the Trust'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 the Trust files with, or submits
 to, the SEC and in other public communications made by the
 Trust;
 - compliance with applicable laws and governmental rules and
 regulations;
 - prompt internal reporting of violations of the Code to the
 Chief Legal Officer of the Trust, the President of the Trust
 (if the violation concerns the Treasurer), the CEO of USAA,
 and if deemed material to the Funds' financial condition or
 reputation, the Chair of the Trust's Board of 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.

 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.
 - 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 the Trust, must be
 approved by the USAA Funds' and Investment Code of Ethics
 Committee and reported to the Trust.
 - the receipt of any non-nominal (I.E., valued over $25) gifts from
 any person or entity with which a Trust 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 the Trust shall be considered the Chief Legal Officer
 of the Trust.
 - 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 Trust's service providers, other
 than IMCO or any other USAA company, must be approved by the CEO
 of USAA and reported to the Trust's 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
 CEO of USAA and reported to the Trust's 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 the Trust.
 - 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'
 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 the Trust 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 the Trust
 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 Trustees. However, any
 approvals or waivers sought by a Covered Officer will be
 reported initially to the CEO of USAA and will be considered by
 the Trust's Board of Trustees.

 B. REQUIRED REPORTS

 - EACH COVERED OFFICER MUST:
 - Upon adoption of the Code, affirm in writing to the
 Board 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
 Trust (if the complaint involves the Treasurer), the CEO of
 USAA and the Chair of the Trust's 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 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 Trust's outside counsel or the counsel to the Independent
 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 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 Trust's 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.
 - The Board of Trustees understands 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
 Trustees will report to the Board 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 the Trust, 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 Investment Code of Ethics (designated to
address 1940 Act and Advisers Act requirements) and IMCO's more detailed
compliance policies and procedures (including its Insider Trading Policy) are
separate requirements applying to Covered Officers and other IMCO employees, and
are not part of this Code. Also, USAA's Code of Conduct imposes separate
requirements on Covered Officers and all employees of USAA, and also is not part
of this Code.

VI. AMENDMENTS

 Any amendment to this Code, other than amendments to Appendix A, must
be approved or ratified by majority vote of the Board of 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 Trust's
Board of Trustees and counsel for the Independent Trustees (if any), the Trust
and its counsel, IMCO, and other personnel of USAA as determined by the Trust's
Chief Legal Officer or the Chair of the Trust's Board of Trustees.
