Investment Objective

The Fund seeks current income consistent with capital preservation.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund.

Shareholder Fees (fees paid directly from your investment)
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	None
Maximum deferred sales charge (load) (as a percentage of offering price)	None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.35%
Distribution (12b-1) Fees	0.00%
Other Expenses	0.13%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses	0.49%
Fee Waivers	0.00%
Total Annual Fund Operating Expenses After Fee Waiver1	0.49%

1. The Manager has contractually committed through December 31, 2017, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund's Total Annual Fund Operating Expenses After Fee Waiver at 0.48% for Institutional Class. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses, and extraordinary expenses are excluded from the cap. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Example of Expenses

The example below is intended to help you compare the costs of investing in the Fund with the costs of investing in other mutual funds. The example assumes a $10,000 initial investment, 5% annual total return, and that fees and expenses remain the same as in the tables above. To the extent that the Manager is waiving fees or reimbursing expenses, the example assumes that such waiver or reimbursement will only be in place through the date noted above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

After:
1 Year	$50
3 Years	$157
5 Years	$274
10 Years	$616

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 59% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in debt securities;

• up to 25% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers; and

• up to 15% of the Fund's total assets in below investment-grade debt securities.

We invest principally in debt securities. We may invest in a variety of debt securities, including corporate, mortgage- and asset-backed securities, bank loans and U.S. Government obligations. These securities may have fixed, floating or variable rates. We invest in both investment-grade and below investment-grade debt securities (often called "high yield securities" or "junk bonds") and may also invest in U.S. dollar-denominated debt securities of foreign issuers. As part of our below investment-grade debt securities investment strategy, we will generally invest in securities that are rated at least BB by Standard & Poor's or Ba by Moody's, or an equivalent quality rating from another Nationally Recognized Statistical Ratings Organization, or are deemed by us to be of comparable quality. We may also use futures for duration and yield curve management. While we may purchase securities of any maturity, under normal circumstances, we expect the Fund's dollar-weighted average effective maturity to be three years or less. "Dollar-Weighted Average Effective Maturity" is a measure of the average time until the final payment of principal and interest is due on fixed income securities in the Fund's portfolio.

We employ a top-down macroeconomic outlook to determine the portfolio's duration, yield curve positioning, credit quality and sector allocation. Macroeconomic factors considered may include, among others, the pace of economic growth, employment conditions, corporate profits, inflation, monetary and fiscal policy, as well as the influence of international economic and financial conditions. In combination with our top-down macroeconomic approach, we employ a bottom-up process of fundamental securities analysis to determine the specific securities for investment. Elements of this evaluation may include credit research, duration measurements, historical yield spread relationships, volatility trends, mortgage refinance rates, as well as other factors. Our credit analysis may consider an issuer's general financial condition, its competitive position and its management strategies, as well as industry characteristics and other factors. We may sell a security due to changes in credit characteristics or outlook, as well as changes in portfolio strategy or cash flow needs. A security may also be sold and replaced with one that presents a better value or risk/reward profile.

Principal Investment Risks

An investment in the Fund may lose money, is not a deposit of Wells Fargo Bank, N.A. or its affiliates, is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, and 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.

Derivatives Risk. The use of derivatives, such as futures, options and swap agreements, can lead to losses, including those magnified by leverage, particularly when derivatives are used to enhance return rather than mitigate risk. Certain derivative instruments may be difficult to sell when the portfolio manager believes it would be appropriate to do so, or the other party to a derivative contract may be unwilling or unable to fulfill its contractual obligations.

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.

Futures Contracts Risk. A Fund that uses futures contracts, which are a type of derivative, is subject to the risk of loss caused by unanticipated market movements. In addition, there may at times be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes and there may at times not be a liquid secondary market for certain futures contracts.

High Yield Securities Risk. High yield securities and unrated securities of similar credit quality (commonly known as "junk bonds") have a much greater risk of default or of not returning principal and their values tend to be more volatile than higher-rated securities with similar maturities.

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.

Loan Risk. Loans may be unrated, less liquid and more difficult to value than traditional debt securities. The highly leveraged capital structure of the borrowers in such transactions may make such loans especially vulnerable to adverse changes in financial, economic or market conditions. A Fund may be unable to sell loans at a desired time or price. The Fund may also not be able to control amendments, waivers or the exercise of any remedies that a lender would have under a direct loan and may assume liability as a lender.

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser 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.

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.

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.
