PRESIDENT'S MESSAGE

"WHEN SELECTING A SPECIFIC SECURITY, WE
STRIVE TO FIND A GOLDEN MEAN BETWEEN THE [PHOTO OF CHRISTOPHER W. CLAUS]
LEVEL OF INCOME, THE CREDIT RISK OF THE ISSUER,
AND THE PRICE VOLATILITY OF THE BOND."


OCTOBER 2009

The reversal in investor sentiment -- from the extreme pessimism of late 2008 to the optimism of 2009 -- has been remarkable.

During 2008, the municipal bond market suffered one of its worst selloffs in history. "Credit spreads," the risk premium between the yield of an investment-grade tax-exempt bond and a comparable U.S. Treasury, widened dramatically amid poor liquidity conditions and distressed selling. Economic conditions deteriorated and unemployment increased. Accordingly, tax revenues declined; however, most municipalities had the political will to address their budgetary challenges and protect their credit standing.

Investors rediscovered the value of municipal securities -- attractive after-tax yields -- beginning in January 2009. The result was strong demand: prices rebounded and yields dropped as credit spreads contracted toward historical norms. (A bond's yield moves in the opposite direction of its price.)

Yields on tax-exempt money markets also declined as the Federal Reserve (the Fed), in an effort to stimulate the economy, cut short-term interest rates nearly to zero. I expect Fed governors to keep rates at these levels until they see evidence of a sustained economic recovery. Consequently, money market yields are unlikely to increase until at least the second half of next year.

At the time of this writing, the economy appears to have stabilized. Housing prices and manufacturing have both shown signs of improvement.


2 | USAA CALIFORNIA MONEY MARKET FUND



Corporate earnings have generally exceeded expectations, but much of the earnings were achieved by cost cutting and inventory reduction. For an economic recovery to take hold, companies must see top line revenue growth, and that depends on the consumer. Unfortunately, the unemployment rate appears to be weighing down consumer confidence. As a result, I expect the economy to experience an extended period of slow growth before it regains its full health.

In the meantime, the after-tax yields on municipal bonds remain attractive. Their tax-exempt status may become even more appealing if the federal and state governments raise taxes.

At USAA, we remain confident in our approach to managing your municipal bond and money market investments. Our primary objective is to distribute a high level of tax-free interest without undue risk of principal. When selecting a specific security, we strive to find a golden mean between the level of income, the credit risk of the issuer, and the price volatility of the bond. Our portfolio managers are supported by a fixed-income research team of experienced analysts. As always, we continue to avoid bonds that are subject to the alternative minimum tax for individuals.

During this uncertain period, like in any other, we encourage our members to be diversified. You also should have an investment plan that meets your individual goals, risk tolerance, and time horizon. Municipal bond prices may have risen, but it is important to remember that the driver of long-term fixed-income performance is the compounding interest of the bonds we hold.

Thank you for your trust in us. We appreciate the opportunity to serve your investment needs.

Sincerely,

/S/ CHRISTOPHER W. CLAUS

President and Vice Chairman of the Board
USAA Mutual Funds Trust

MANAGER'S COMMENTARY ON THE FUND

REGINA SHAFER, CFA [PHOTO OF REGINA SHAFER]
USAA Investment Management Company


o HOW DID THE USAA CALIFORNIA MONEY MARKET FUND (THE FUND) PERFORM FROM MARCH 31, 2009, TO SEPTEMBER 30, 2009?

The Fund performed well for the reporting period ended September 30, 2009. During the reporting period, the Fund ranked 6 out of 162 state-specific tax exempt money market funds, according to iMoneyNet, Inc. The Fund had a return of 0.19%, compared to the average return of the category of 0.05%. The Fund also ranked 3 out of 72 California tax-exempt money market funds, and returned 0.19% where the category's average return was 0.05%. Rankings are based on six-month net compound unannualized returns.

o WHAT WERE THE MARKET CONDITIONS?

To maintain liquidity in the markets, the Federal Reserve (the Fed) held the federal funds target rate at a range between 0% and 0.25% throughout the reporting period. The economy showed signs of improvement, suggesting the worst of the recession might be over.

Yields on short-term tax-exempt securities dropped as demand overwhelmed supply. Investors flocked to the safety of money

market funds, apparently content to remain on the sidelines until the financial markets stabilized. Demand was strong for municipal variable-rate demand notes (VRDNs). The Bond Buyer One-Year Note Index averaged 0.71% during the reporting period. The SIFMA Municipal Swap Index, the index of seven-day VRDNs, started the reporting period at 0.54% on March 31, 2009, reaching a low of 0.27% on July 8, 2009, and ended the reporting period at 0.34%.

o WHAT ARE THE CONDITIONS IN THE STATE OF CALIFORNIA?

The recession continued to weigh on California's economy. Unemployment spiked to over 12% during the course of the reporting period and the real estate market remained sluggish. Despite declining revenues, lawmakers successfully reached compromises that alleviated the state's immediate budget pressures. Because of continuing budgetary pressures, California's general obligation bonds were downgraded; at the end of the reporting period, they were rated Baa1 by Moody's Investors Service, A by Standard & Poor's Rating Services, and BBB by Fitch Ratings Ltd.

o WHAT WERE YOUR STRATEGIES IN THIS ENVIRONMENT?

To maintain the safety and liquidity of your Fund, we concentrated our purchases in VRDNs. The VRDNs owned by the Fund possess a feature guaranteeing the payment of both principal and interest. In addition, they provide flexibility because they can be sold at par value (100% of face value) with a notice of seven days or less. At the end of the reporting period, the portfolio's weighted average maturity (WAM) was 13 days.

The Bond Buyer One-Year Note Index is based on estimated yields for theoretical new one-year note issues from 10 state and local issuers:
California, Colorado, Idaho, Los Angeles County, Michigan, New Jersey, New York City, Pennsylvania, Texas, and Wisconsin. The index is an unweighted average of the average estimated bid-side yields for the 10 issues.

The Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Index, produced by Municipal Market Data, is a seven-day high-grade market index comprised of tax-exempt variable-rate demand obligations from Municipal Market Data's extensive database.


MANAGER'S COMMENTARY ON THE FUND | 5



As always, we relied on our seasoned team of credit analysts to evaluate and monitor each of the Fund's holdings. Their hard work has enabled us to avoid credit problems in our tax-exempt money market funds in one of most difficult credit periods in decades.

o WHAT IS THE OUTLOOK?

We expect the Fed to continue supporting the U.S. economy and the credit markets. With no immediate threat of inflation, we believe short-term rates are likely to remain low until at least the middle of 2010. Once rate increases begin, we believe they will be gradual with the shortest maturities benefiting first.

We will continue to focus on maintaining the safety and liquidity of your Fund, while striving to maximize the tax-exempt income you receive. To make the Fund as tax efficient as possible, we also will continue to avoid issues subject to the alternative minimum tax, also known as the AMT, for individuals.

Thank you for the confidence you have placed in us.

o CATEGORIES AND DEFINITIONS

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 reflect current market conditions. The effective maturity of these instruments is deemed to be less than 397 days in accordance with detailed regulatory requirements.

PUT BONDS -- provide the right to sell the bond at face value at specific tender dates prior to final maturity. The put feature shortens the effective maturity of the security.

FIXED-RATE INSTRUMENTS -- consist of municipal bonds, notes, and commercial paper. The interest rate is constant to maturity. Prior to maturity, the market price of a fixed-rate instrument generally varies inversely to the movement of interest rates.

CREDIT ENHANCEMENTS -- add the financial strength of the provider of the enhancement to support the issuer's ability to repay the principal and interest payments when due. The enhancement may be provided by a high-quality bank, insurance company or other corporation, or a collateral trust. The enhancements do not guarantee the values of the securities.

The Fund's investments consist of securities meeting the requirements to qualify at the time of purchase as "eligible securities" under the Securities and Exchange Commission (SEC) rules applicable to money market funds. With respect to quality, eligible securities generally consist of securities rated in one of the two highest categories for short-term securities or, if not rated, of comparable quality at the

time of purchase. USAA Investment Management Company (the Manager) also attempts to minimize credit risk in the Fund through rigorous internal credit research.

(INS) Principal and interest payments are insured by one of the following:

 Assured Guaranty Corp., Berkshire Hathaway Assurance Corp., Financial
 Security Assurance, Inc., or National Indemnity Co. Although bond
 insurance reduces the risk of loss due to default by an issuer, such
 bonds remain subject to the risk that value may fluctuate for other
 reasons, and there is no assurance that the insurance company will
 meet its obligations.

(LIQ) Liquidity enhancement that may, under certain circumstances, provide
 for repayment of principal and interest upon demand from one of the
 following: Bank of America, N.A., Citibank, N.A., Citigroup, Inc.,
 Deutsche Bank A.G., Deutsche Postbank, Dexia Credit Local, JPMorgan
 Chase & Co., JPMorgan Chase Bank, N.A., Merrill Lynch & Co., Inc.,
 Morgan Stanley, Rabobank Nederland N.V., Societe Generale, SunTrust
 Bank, Wachovia Bank, N.A., or Wells Fargo & Co.

(LOC) Principal and interest payments are guaranteed by a bank letter of
 credit or other bank credit agreement.

(NBGA) Principal and interest payments or, under certain circumstances, underlying mortgages are guaranteed by a nonbank guarantee agreement from Merrill Lynch & Co., Inc.

NOTES TO FINANCIAL STATEMENTS

September 30, 2009 (unaudited)


(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 45 separate funds. The information presented in this semiannual report pertains only to the USAA California Money Market Fund (the Fund), which is classified as diversified under the 1940 Act. The Fund's investment objective is to provide investors with a high level of current interest income that is exempt from federal and California state income taxes, with a further objective of preserving capital and maintaining liquidity.

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. Pursuant to Rule 2a-7 under the 1940 Act, securities in the Fund are valued at amortized cost, which approximates market value. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or discounts.

2. Securities for which amortized cost valuations are considered unreliable or whose values have been materially affected by a significant event are valued in good faith at fair value, using methods determined by USAA Investment Management Company (the Manager), an affiliate of the Fund, under valuation procedures and procedures to stabilize net asset value (NAV) approved by the Trust's Board of Trustees.


NOTES TO FINANCIAL STATEMENTS | 21



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. For example, money market securities are valued using amortized cost, in accordance with rules under the 1940 Act. Generally, amortized cost approximates the current fair value of a security, but since the value is not obtained from a quoted price in an active market, such securities are reflected as Level 2.

C. 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.

D. INVESTMENTS IN SECURITIES -- Security transactions are accounted for on the date the securities are purchased or sold (trade date). Gains or losses from sales of investment securities are computed on the identified cost basis. Interest income is recorded daily on the accrual basis. Premiums and discounts are amortized over the life of the


22 | USAA CALIFORNIA MONEY MARKET FUND



respective securities using the straight-line method. The Fund concentrates its investments in California tax-exempt securities and, therefore, may be exposed to more credit risk than portfolios with a broader geographical diversification.

E. SECURITIES PURCHASED ON A DELAYED-DELIVERY OR WHEN-ISSUED BASIS -- Delivery and payment for securities that have been purchased by the Fund on a delayed-delivery or when-issued basis can take place a month or more after the trade date. During the period prior to settlement, these securities do not earn interest, are subject to market fluctuation, and may increase or decrease in value prior to their delivery. The Fund maintains segregated assets with a market value equal to or greater than the amount of its purchase commitments.

F. GUARANTEE PROGRAM -- Subject to certain terms and conditions, the U.S.
Department of the Treasury's Temporary Guarantee Program for Money Market Funds (the Program) provided coverage to shareholders for amounts held in participating money market funds as of the close of business on September 19, 2008, for the term of the Program of September 19, 2008, through September 18, 2009 (Program Term). The Fund was responsible for payment of fees required to continue its participation in the Program without regard to any waivers or expense limitations in effect for the Fund. The participation fee for the Program Term was 0.04% of the number of shares outstanding of the Fund as of September 19, 2008. For the six-month period ended September 30, 2009, the Fund recorded $119,000, as guarantee program fee on the statement of operations. Effective September 18, 2009, the Program has expired.

G. EXPENSES PAID INDIRECTLY -- Through arrangements with the Fund's custodian and other banks utilized by the Fund for cash management purposes, realized credits, if any, generated from cash balances in the Fund's bank accounts may be used to directly reduce the Fund's expenses. For the six-month period ended September 30, 2009, these custodian and other bank credits reduced the Fund's expenses by less than $500.


NOTES TO FINANCIAL STATEMENTS | 23



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 $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 0.07% annually 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 six-month period ended September 30, 2009, the Fund paid CAPCO facility fees of $2,000, which represents 1.8% of the total fees paid to CAPCO by the USAA funds. The Fund had no borrowings under this agreement during the six-month period ended September 30, 2009.


24 | USAA CALIFORNIA MONEY MARKET FUND



(3) DISTRIBUTIONS

The tax basis of distributions and accumulated undistributed net investment income will be determined based upon the Fund's tax year-end of March 31, 2010, in accordance with applicable tax law.

Net investment income is accrued daily as dividends and distributed to shareholders monthly. Distributions of realized gains from security transactions not offset by capital losses are made annually in the succeeding fiscal year or as otherwise required to avoid the payment of federal taxes.

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 six-month period ended September 30, 2009, the Fund did not incur any income tax, interest, or penalties. As of September 30, 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 March 31, 2006, through March 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) TRANSACTIONS WITH MANAGER

A. MANAGEMENT FEES -- The Manager carries out the Fund's investment policies and manages the Fund's portfolio pursuant to an Advisory Agreement. The Fund's management fees are accrued daily and paid monthly as a percentage of aggregate average net assets of the USAA California Bond and USAA California Money Market funds combined, which on an annual basis is equal to 0.50% of the first $50 million, 0.40% of that portion over $50 million but not over $100 million, and 0.30% of that portion over $100 million. These


NOTES TO FINANCIAL STATEMENTS | 25



fees are allocated on a proportional basis to each Fund monthly based upon average net assets. For the six-month period ended September 30, 2009, the Fund incurred total management fees, paid or payable to the Manager, of $916,000, resulting in an effective annualized management fee of 0.31% of the Fund's average net assets for the same period.

B. ADMINISTRATION AND SERVICING FEES -- The Manager provides certain administration and shareholder servicing functions for the Fund. For such services, the Manager receives a fee accrued daily and paid monthly at an annualized rate of 0.10% of the Fund's average net assets. For the six-month period ended September 30, 2009, the Fund incurred administration and servicing fees, paid or payable to the Manager, of $293,000.

In addition to the services provided under its Administration and Servicing Agreement with the Fund, the Manager also provides 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 six-month period ended September 30, 2009, the Fund reimbursed the Manager $15,000 for these compliance and legal services. These expenses are included in the professional fees on the Fund's statement of operations.

C. TRANSFER AGENT'S FEES -- USAA Transfer Agency Company, d/b/a USAA Shareholder Account Services (SAS), an affiliate of the Manager, provides transfer agent services to the Fund based on an annual charge of $25.50 per shareholder account plus out-of-pocket expenses. The Fund also pays SAS fees that are related to the administration and servicing of accounts that are traded on an omnibus basis. For the six-month period ended September 30, 2009, the Fund incurred transfer agent's fees, paid or payable to SAS, of $176,000.

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


26 | USAA CALIFORNIA MONEY MARKET FUND



(5) TRANSACTIONS WITH AFFILIATES

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

(6) SUBSEQUENT EVENTS

Events or transactions that occur after the balance sheet date but before the financial statements are issued are categorized as recognized or non-recognized for financial statement purposes. The Manager has evaluated subsequent events through November 17, 2009, the date the financial statements were issued, and has determined there were no events that required recognition or disclosure in the Fund's financial statements. Subsequent events that will affect future financial statements are as follows:

The Manager has voluntarily agreed, on a temporary basis, to reimburse management, administrative, or other fees to limit the Fund's expenses in order to distribute a minimum annualized daily yield of 0.01%. The Manager can modify or terminate this arrangement at any time.

(7) NEW ACCOUNTING PRONOUNCEMENT

DERIVATIVES AND HEDGING -- In March 2008, the Financial Accounting Standards Board issued an accounting standard that requires 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. The accounting standard is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. The Manager has evaluated the accounting standard, and due to the Fund's investment restrictions pertaining to derivative instruments, has determined that there is no impact on the Fund's financial statement disclosures.

EXPENSE EXAMPLE

September 30, 2009 (unaudited)


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 April 1, 2009, through September 30, 2009.

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


EXPENSE EXAMPLE | 29



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.

ADVISORY AGREEMENT

September 30, 2009 (unaudited)


At a meeting of the Board of Trustees (the Board) held on April 16, 2009, the Board, including the Trustees who are not "interested persons" of the Trust (the Independent Trustees), approved the continuance of the Advisory Agreement between the Trust and the Manager with respect to the Fund.

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

and profitability. However, the Board noted that the evaluation process with respect to the Manager is an ongoing one. In this regard, the Board's and its committees' consideration of the Advisory Agreement included information previously received at such meetings.

ADVISORY AGREEMENT

After full consideration of a variety of factors, the Board, including the Independent Trustees, voted to approve the Advisory Agreement. In approving the 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 Advisory Agreement, the Board 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 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 Advisory Agreement. The Board considered the level and depth of knowledge of the Manager, including the professional experience and qualifications of its senior and investment personnel, as well as current staffing levels. The allocation of the Fund's brokerage, including the Manager's process for monitoring "best execution," also was considered. The Manager's role in coordinating the activities of the

Fund's other service providers also was 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 Advisory Agreement. In reviewing the 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 and its affiliates, including the Manager's oversight of the Fund's day-to-day operations and oversight of Fund accounting. The Trustees, guided also by information obtained from their experiences as 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 Advisory Agreement, the Board evaluated the Fund's advisory fees and total expense ratio as compared to other open-end investment companies deemed to be comparable to the Fund as determined by the independent third party in its report. The Fund's expenses were compared to (i) a group of investment companies chosen by the independent third party to be comparable to the Fund based upon certain factors, including fund type, comparability of investment objective and classification, sales load type (in this case, investment companies with no sales loads), asset size, and expense components (the "expense group") and (ii) a larger group of investment companies that includes the Fund and all other 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 -- was above the median of its expense group and its expense universe. The data indicated that the Fund's total expense ratio was the lowest of its expense group and below the median of its expense universe. The Board took into account the various services provided to the Fund by the Manager and its affiliates, including the nature and high quality of the services provided by the Manager. The Board also noted the level and method of computing the management fee.


ADVISORY AGREEMENT | 33



In considering the Fund's performance, the Board noted that it 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 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 California tax-exempt money market funds regardless of asset size or primary channel of distribution. This comparison indicated that the Fund's performance was above the average of its performance universe and its Lipper index for the one-, three-, and five-year periods ended December 31, 2008. The Board also noted that the Fund's percentile performance ranking was in the top 20% of its performance universe for the same periods.

COMPENSATION AND PROFITABILITY -- The Board took into consideration the level and method of computing the management fee. The information considered by the Board included operating profit margin information for the Manager's business as a whole. The Board also received and considered profitability information related to the management revenues from the Fund. This consideration included a broad review of the methodology used in the allocation of certain costs to the Fund. The Trustees reviewed the profitability of the Manager's relationship with the Fund before tax expenses. In reviewing the overall profitability of the management fee to the Manager, the Board also considered the fact that affiliates provide shareholder servicing and administrative services to the Fund for which they receive compensation. The Board also considered the possible direct and indirect benefits to the Manager from its relationship with the Trust, including that the Manager may derive reputational and other benefits from its association with the Fund. The Board also took into account the high quality of services received by the Fund from the Manager as well as the type of fund. The Trustees recognized that the Manager should be entitled to earn a reasonable level of profits in exchange for the level of services it provides to the Fund and the entrepreneurial risk that it assumes as Manager.

ECONOMIES OF SCALE -- The Board noted that the Fund has advisory fee breakpoints that allow the Fund to participate in economies of scale and that such economies of scale currently were reflected in the advisory fee. The Board also noted that the Fund's contractual management fee is below or comparable to the asset-weighted average of funds up to $3 billion in its peer group as set forth in the report prepared by the independent third party. The Board also considered the effect of the Fund's growth and size on its performance and fees, noting that the Fund may realize additional economies of scale if assets increase proportionally more than some expenses. The Board determined that the current investment management fee structure was reasonable.

CONCLUSIONS -- The Board reached the following conclusions regarding the Fund's 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 Advisory Agreement; (ii) the Manager maintains an appropriate compliance program; (iii) the performance of the Fund is reasonable in relation to the performance of funds with similar investment objectives and to relevant indices; (iv) the Fund's advisory expenses are reasonable in relation to those of similar funds and to the services to be provided by the Manager; and (v) the Manager's level of profitability from its relationship with the Fund is reasonable in light of the nature and high quality of services provided by the Manager and the type of fund. Based on its conclusions, the Board determined that continuation of the Advisory Agreement would be in the best interests of the Fund and its shareholders.
