(WFA Income Funds - Classes A and C) | (Wells Fargo Core Bond Fund)

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Investment Objective </b></p>

The Fund seeks total return, consisting of income and capital appreciation.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Fees and Expenses </b></p>

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. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the aggregate in specified classes of certain Wells Fargo Funds. More information about these and other discounts is available from your financial professional and in "Share Class Features" and "Reductions and Waivers of Sales Charges" on pages 22 and 23 of the Prospectus and "Additional Purchase and Redemption Information" on page 67 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 39 for further information.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Shareholder Fees (fees paid directly from your investment) </b></p>

Shareholder Fees - ­ - (Wells Fargo Core Bond Fund)	Class A		Class C
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	4.50%		none
Maximum deferred sales charge (load) (as a percentage of offering price)	none	[1]	1.00%

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)</b></p>

Annual Fund Operating Expenses - ­ - (Wells Fargo Core Bond Fund)		Class A	Class C
Management Fees	[1]	0.39%	0.39%
Distribution (12b-1) Fees		none	0.75%
Other Expenses		0.44%	0.44%
Total Annual Fund Operating Expenses	[2]	0.83%	1.58%
Fee Waivers		(0.05%)	(0.05%)
Total Annual Fund Operating Expenses After Fee Waivers	[3]	0.78%	1.53%

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Example of Expenses </b></p>

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:

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Assuming Redemption at End of Period </b></p>

Expense Example - (Wells Fargo Core Bond Fund) - ­ - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	526	698	885	1,425
Class C	256	494	856	1,874

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Assuming No Redemption </b></p>

Expense Example, No Redemption - (Wells Fargo Core Bond Fund)	1 Year	3 Years	5 Years	10 Years
Class C | ­ | USD ($)	156	494	856	1,874

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Portfolio Turnover </b></p>

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 542% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Performance </b></p>

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Portfolio Turnover </b></p>

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 29% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

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:

Expense Example - (Wells Fargo Core Bond Fund)	1 Year	3 Years	5 Years	10 Years

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Portfolio Turnover </b></p>

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 542% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

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:

Expense Example - (Wells Fargo Real Return Fund)	1 Year	3 Years	5 Years	10 Years

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Portfolio Turnover </b></p>

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 29% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

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 542% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

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:

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Portfolio Turnover </b></p>

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 29% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

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.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

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.

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

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 542% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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.

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.

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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

Portfolio Turnover [Text Block]

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 29% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

Risk [Heading]

rr_RiskHeading

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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 29% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

rr_RiskHeading

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

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:

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Portfolio Turnover </b></p>

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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 542% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

Risk [Heading]

rr_RiskHeading

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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 542% of the average value of its portfolio.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 80% of the Fund's total assets in investment-grade debt securities;

• up to 25% of the Fund's total assets in asset-backed securities, other than mortgage-backed securities; and

• up to 20% of the Fund's total assets in U.S. dollar-denominated debt securities of foreign issuers.

The Fund is a gateway fund that invests substantially all of its assets in the Core Bond Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We invest principally in investment-grade debt securities, including U.S. Government obligations, corporate bonds and mortgage- and asset-backed securities. As part of our investment strategy, we may enter into mortgage dollar rolls and reverse repurchase agreements, as well as invest in U.S. dollar-denominated debt securities of foreign issuers. We may also use futures, options or swap agreements to manage risk or to enhance return or as a substitute for purchasing the underlying security. While we may purchase securities of any maturity or duration, under normal circumstances, we expect to maintain an overall portfolio dollar-weighted average effective duration that is within 10% of that of the Fund's benchmark. The Fund's benchmark, the Bloomberg Barclays U.S. Aggregate Bond index, had a duration of 5.85 years, as of August 31, 2017. "Dollar-Weighted Average Effective Duration" is an aggregate measure of the sensitivity of a fund's fixed income portfolio securities to changes in interest rates. As a general matter, the price of a fixed income security with a longer effective duration will fluctuate more in response to changes in interest rates than the price of a fixed income security with a shorter effective duration.

We invest in debt securities that we believe offer competitive returns and are undervalued, offering additional income and/or price appreciation potential relative to other debt securities of similar credit quality and interest rate sensitivity. From time to time, we may also invest in unrated bonds that we believe are comparable to investment-grade debt securities. We may sell a security that has achieved its desired return or if we believe the security or its sector has become overvalued. We may also sell a security if a more attractive opportunity becomes available or if the security is no longer attractive due to its risk profile or as a result of changes in the overall market environment.

Risk [Heading]

rr_RiskHeading

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Risks </b></p>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

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 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.

Options Risk. A Fund that purchases options, which are a type of derivative, is subject to the risk of a loss of premiums without offsetting gains. A Fund that writes options receives a premium that may be small relative to the loss realized in the event of adverse changes in the value of the underlying instruments.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Principal Investment Strategies </b></p>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

• at least 65% of the Fund's total assets in inflation-indexed debt securities;

• up to 20% of the Fund's total assets in below investment-grade debt securities;

• up to 15% of the Fund's total assets in debt securities of foreign-issuers, including issuers from emerging markets; and

• up to 20% of the Fund's total assets in equity securities, including common and preferred stock, of domestic and foreign issuers, including issuers from emerging markets.

The Fund is a gateway fund that invests substantially all of its assets in the Real Return Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We may invest in additional master portfolios, in other Wells Fargo Funds, or directly in a portfolio of securities.

We utilize an active allocation strategy to diversify the portfolio across various investments, assets and sectors, in an attempt to generate a real return (a return in excess of the rate of inflation) over an economic cycle, consistent with an appropriate level of risk. We allocate investments to various broad asset classes based on our assessment of changing economic, global market, industry, and issuer conditions. We use a "top-down" analysis of macroeconomic trends combined with a "bottom-up" fundamental analysis of market sectors, industries, and issuers to seek to take advantage of varying sector reactions to the economic environment. In implementing the active allocation strategy, we evaluate relative risk and relative values across asset classes, countries, sectors, and issuers.

We invest principally in debt securities, seeking to exceed the rate of inflation over a full market cycle. These securities may have fixed, floating or variable rates and may include debt securities of both domestic and foreign issuers, including issuers from emerging markets. We invest primarily in inflation-indexed debt securities issued or guaranteed by governments, their agencies or instrumentalities, as well as corporate issuers. We may also invest in a variety of other debt securities, including corporate, mortgage- and asset-backed securities, bank loans and government obligations. We treat the returns from inflation-indexed debt securities as including interest paid on the principal amount of the security, adjustments made to the principal amount based on an official inflation measure and changes in market value.

We invest in investment-grade debt securities by generally purchasing securities that we believe have strong relative value based on an analysis of a security's characteristics (such as its principal value, coupon rate, credit quality, maturity, duration and yield) in light of the current market environment. We may also invest in below investment-grade debt securities, often called "high yield securities" or "junk bonds". We start our investment process with a focus on bottom-up fundamental credit analysis to generate investment ideas, to understand the potential risks, and to select individual securities that may potentially add value from income and/or capital appreciation. Our credit research may include an assessment of an issuer's general financial condition, its competitive positioning and management strength, as well as industry characteristics and other factors. We may sell a debt security due to changes in credit characteristics or our outlook, as well as changes in portfolio strategy or cash flow needs or to replace a debt security with another security that presents what we believe to be a better value or risk/reward profile. We do not manage the Fund's portfolio to a specific maturity or duration.

We may invest in equity securities, including common and preferred stocks, of domestic and foreign issuers, including emerging market issuers and American Depositary Receipts (ADRs). We seek out investments that we believe have strong financial attributes and offer compelling valuation opportunities. We may invest in equity securities of companies of any size. These investments will generally be within sectors of the market that we believe to be inflation-sensitive.

We may invest in derivatives, such as futures and swaps that have economic or financial characteristics that are similar to inflation-indexed, debt securities or equity securities. We may also use futures contracts to manage or adjust duration and yield curve exposure, as well as to manage risk or to enhance return.

We may enter into currency-related transactions through derivative instruments, including currency and cross currency forwards. The use of derivative currency transactions is intended to allow the Fund to manage, hedge or reduce a foreign currency-specific risk exposure of a portfolio security or its denominated currency or to obtain net long exposure to selected currencies for the purpose of generating income or additional returns.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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.

Emerging Markets Risk. Emerging market securities typically present even greater exposure to the risks described under "Foreign Investment Risk" and may be particularly sensitive to global economic conditions. Emerging market securities are also typically less liquid than securities of developed countries and could be difficult to sell, particularly during a market downturn.

Foreign Currency Contracts Risk. A Fund that enters into forwards or other foreign currency contracts, which are a type of derivative, is subject to the risk that the portfolio manager may be incorrect in his or her judgment of future exchange rate changes.

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.

Inflation-Indexed Debt Securities Risk. The principal value of an inflation-indexed debt security is periodically adjusted according to the rate of inflation and, as a result, the value of a Fund's yield and return will be affected by changes in the rate of inflation.

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.

Smaller Company Securities Risk. Securities of companies with smaller market capitalizations tend to be more volatile and less liquid than those of larger companies.

Swaps Risk. Depending on their structure, swap agreements and options to enter into swap agreements ("swaptions"), both of which are types of derivatives, may increase or decrease a Fund's exposure to long- or short-term interest rates, foreign currency values, mortgage-backed securities, corporate borrowing rates, or credit events or other reference points such as security prices or inflation rates.

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.
