Principal Investment Strategies Under normal circumstances, we invest: exclusively in high-quality, short-term, U.S. dollar-denominated money market instruments of domestic and foreign issuers. These instruments include, but are not limited to, bank obligations such as time deposits and certificates of deposit, government securities, asset-backed securities, commercial paper, corporate bonds, municipal securities and repurchase agreements. These investments may have fixed, floating, or variable rates of interest and may be obligations of U.S. or foreign issuers. We may invest more than 25% of the Fund's total assets in U.S. dollar-denominated obligations of U.S. banks. Our security selection is based on several factors, including credit quality, yield and maturity, while taking into account the Fund's overall level of liquidity and weighted average maturity. We will only purchase securities that we have determined present minimal credit risk. Principal Investment Risks You could lose money by investing in the Fund. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The Fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund's liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not a deposit of Wells Fargo Bank, N.A. or its affiliates and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. The Fund is primarily subject to the risks briefly summarized below. Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money. Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes. Industry Concentration Risk. A Fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly. Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase. Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or subadviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives. Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments. Money Market Fund Risk. The Fund's yield will change based on changes in interest rates and other market conditions. Because the Fund invests in short-term instruments, the Fund's dividend yields are expected to be low when short-term market interest rates are low. Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns. Municipal Securities Risk. Municipal securities may be fully or partially backed or enhanced by the taxing authority of a local government, by the current or anticipated revenues from a specific project or specific assets, or by the credit of, or liquidity enhancement provided by, a private issuer. Various types of municipal securities are often related in such a way 3 Wells Fargo Funds - Money Market Funds

that political, economic or business developments affecting one obligation could affect other municipal securities held by a Fund. Repurchase Agreement Risk. In the event that the counterparty to a repurchase agreement is unwilling or unable to fulfill its contractual obligations to repurchase the underlying security, a Fund may lose money, suffer delays, or incur costs arising from holding or selling the underlying security. U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

Principal Investment Strategies Under normal circumstances, we invest: exclusively in high-quality, short-term, U.S. dollar-denominated money market instruments; and at least 80% of the Fund s net assets are invested in municipal obligations that pay interest exempt from regular federal income tax, but not necessarily the federal alternative minimum tax ( AMT ). We may also invest: any amount in securities that pay interest subject to federal AMT. We actively manage a portfolio of high-quality, short-term municipal obligations that are issued by or on behalf of states, territories and possessions of the U.S. or their political subdivisions and financing authorities. These investments may have fixed, floating, or variable rates of interest. We invest principally in municipal obligations that pay interest exempt from regular federal income tax, but not necessarily federal AMT. The Fund attempts to invest exclusively in these securities.

Our security selection is based on several factors, including credit quality, yield and maturity, while taking into account the Fund's overall level of liquidity and weighted average maturity.

The Fund may temporarily invest a greater portion of assets in high-quality, short-term money market instruments that pay interest subject to regular federal income tax or by holding a greater portion of assets in uninvested cash. Circumstances in which the Fund may invest or hold a greater portion of its assets in these securities or uninvested cash include, but are not limited to, periods of low or no availability of eligible municipal obligations or in order to manage liquidity. During these periods, the Fund may not achieve its objective. To the extent that the Fund invests in taxable securities, it may distribute taxable income. Principal Investment Risks The Fund is primarily subject to the risks mentioned below. Credit Risk Interest Rate Risk Management Risk Market Risk Money Market Fund Risk Municipal Securities Risk These and other risks could cause you to lose money in your investment in the Fund and could adversely affect the Fund's net asset value, yield and total return. These risks are described in the "Description of Principal Investment Risks" section. 17 Wells Fargo Funds - Money Market Funds

Description of Principal Investment Risks Understanding the risks involved in mutual fund investing will help you make an informed decision that takes into account your risk tolerance and preferences. The risks that are most likely to have a material effect on a particular Fund as a whole are called "principal risks." The principal risks for each Fund have been previously identified and are described below. Additional information about the principal risks is included in the Statement of Additional Information. Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due. In these instances, the value of an investment could decline and the Fund could lose money. Credit risk increases as an issuer's credit quality declines. Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign companies may be subject to significantly higher levels of taxation than U.S. companies, including potentially confiscatory levels of taxation, thereby reducing the earnings potential of such foreign companies. Foreign investments may involve exposure to changes in foreign currency exchange rates. Such changes may reduce the U.S. dollar value of the investments. Foreign investments may be subject to additional risks such as potentially higher withholding and other taxes, and may also be subject to greater trade settlement, custodial, and other operational risks than domestic investments. Certain foreign markets may also be characterized by less stringent investor protection and disclosure standards. Industry Concentration Risk. A Fund that concentrates its investments in an industry or group of industries is more vulnerable to adverse market, economic, regulatory, political or other developments affecting such industry or group of industries than a fund that invests its assets more broadly. Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. The longer the terms of the debt securities held by a Fund, the more the Fund is subject to this risk. If interest rates decline, interest that the Fund is able to earn on its investments in debt securities may also decline, which could cause the Fund to reduce the dividends it pays to shareholders, but the value of those securities may increase. Some debt securities give the issuers the option to call, redeem or prepay the securities before their maturity dates. If an issuer calls, redeems or prepays a debt security during a time of declining interest rates, the Fund might have to reinvest the proceeds in a security offering a lower yield, and therefore might not benefit from any increase in value as a result of declining interest rates. Changes in market conditions and government policies may lead to periods of heightened volatility in the debt securities market, reduced liquidity for certain Fund investments and an increase in Fund redemptions. Interest rate changes and their impact on the Fund and its share price can be sudden and unpredictable. Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or subadviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives. Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments. Money Market Fund Risk. The Fund's yield will change based on changes in interest rates and other market conditions. Because the Fund invests in short-term instruments, the Fund's dividend yields are expected to be low when short-term market interest rates are low. Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities are subject to risk of default on the underlying mortgages or assets, particularly during periods of economic downturn. Defaults on the underlying mortgages or assets may cause such securities to decline in value and become less liquid. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. As a result, in a period of rising interest rates, these securities may exhibit additional volatility. When interest rates decline or are low, borrowers may pay off their mortgage or other debts sooner than expected, which can reduce the returns of a Fund. Funds that may enter into mortgage dollar roll transactions are subject to the risk that the market value of the securities that are required to be repurchased in the future may decline below the agreed upon repurchase price. They also involve the risk that the party to whom the securities are sold may become insolvent, limiting a Fund's ability to repurchase securities at the agreed upon price. Municipal Securities Risk. Municipal securities may be fully or partially backed or enhanced by the taxing authority of a local government, by the current or anticipated revenues from a specific project or specific assets, or by the credit of, or liquidity enhancement provided by, a private issuer. Municipal securities may be difficult to obtain because of limited Wells Fargo Funds - Money Market Funds 18
