(Wells Fargo Allocation Funds - Administrator Class) | (Wells Fargo Growth Balanced 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 capital appreciation and current income.

<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.

<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 Growth Balanced Fund)	Administrator Class ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of offering price)	none

<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>

^[1]

Annual Fund Operating Expenses - (Wells Fargo Growth Balanced Fund)	Administrator Class ­
Management Fees	0.30%
Distribution (12b-1) Fees	none
Other Expenses	0.46%
Acquired Fund Fees and Expenses	0.51%
Total Annual Fund Operating Expenses	1.27%
Fee Waivers	(0.32%)
Total Annual Fund Operating Expenses After Fee Waiver	0.95%	[1]

<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:

Expense Example - (Wells Fargo Growth Balanced Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	97	371	666	1,506

<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 114% 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>

We seek to achieve the Fund's investment objective by allocating up to 75% of its assets to equity securities and up to 45% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 65% of the Fund's total assets in stock funds; and

• 35% of the Fund's total assets in bond funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

In addition, certain of the fixed income and equity master portfolios in which the Fund may invest may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

Portfolio Asset Allocation

The following table provides the Fund's neutral allocation and target ranges.

Asset Class	Neutral Position	Range1
Stock Funds	65%	55% to 75%
Bond Funds	35%	25% to 45%
Tactical Asset Allocation Overlay (TAA)	0%	-10% to 10%

1. Negative values represent short positions in futures contracts that may be taken using the applicable overlay strategy.

<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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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.

<p style="font-size:10pt;padding-top:2;padding-bottom:0;padding-left:0;"><b> Performance </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 113% 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>

We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to equity securities and up to 70% of its assets to fixed income securities.

<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:

Expense Example - (Wells Fargo Moderate Balanced 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 113% 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>

We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to equity securities and up to 70% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 60% of the Fund's total assets in bond funds; and

• 40% of the Fund's total assets in stock funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

In addition, certain of the fixed income and equity master portfolios in which the Fund invests may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

Portfolio Asset Allocation

The following table provides the Fund's neutral allocation and target ranges.

Asset Class	Neutral Position	Range1
Bond Funds	60%	50% to 70%
Stock Funds	40%	30% to 50%
Tactical Asset Allocation Overlay (TAA)	0%	-10% to 10%

1. Negative values represent short positions in futures contracts that may be taken using the applicable overlay strategy.

<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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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.

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 21 and 22 of the Prospectus and "Additional Purchase and Redemption Information" on page 59 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.

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 Moderate Balanced Fund) - ­ - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	685	953	1,242	2,060
Class C	293	632	1,098	2,387

<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 113% 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>

We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to equity securities and up to 70% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 60% of the Fund's total assets in bond funds; and

• 40% of the Fund's total assets in stock funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

In addition, certain of the fixed income and equity master portfolios in which the Fund invests may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

Portfolio Asset Allocation

The following table provides the Fund's neutral allocation and target ranges.

Asset Class	Neutral Position	Range1
Bond Funds	60%	50% to 70%
Stock Funds	40%	30% to 50%
Tactical Asset Allocation Overlay (TAA)	0%	-10% to 10%

1. Negative values represent short positions in futures contracts that may be taken using the applicable overlay strategy.

<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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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.

We seek to achieve the Fund's investment objective by allocating up to 75% of its assets to equity securities and up to 45% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 65% of the Fund's total assets in stock funds; and

• 35% of the Fund's total assets in bond funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

In addition, certain of the fixed income and equity master portfolios in which the Fund may invest may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

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.

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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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:

rr_PortfolioTurnoverHeading

<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 113% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to equity securities and up to 70% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 60% of the Fund's total assets in bond funds; and

• 40% of the Fund's total assets in stock funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

In addition, certain of the fixed income and equity master portfolios in which the Fund invests may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

Portfolio Asset Allocation

The following table provides the Fund's neutral allocation and target ranges.

Asset Class	Neutral Position	Range1
Bond Funds	60%	50% to 70%
Stock Funds	40%	30% to 50%
Tactical Asset Allocation Overlay (TAA)	0%	-10% to 10%

1. Negative values represent short positions in futures contracts that may be taken using the applicable overlay strategy.

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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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 113% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to equity securities and up to 70% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 60% of the Fund's total assets in bond funds; and

• 40% of the Fund's total assets in stock funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

In addition, certain of the fixed income and equity master portfolios in which the Fund invests may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

Portfolio Asset Allocation

The following table provides the Fund's neutral allocation and target ranges.

Asset Class	Neutral Position	Range1
Bond Funds	60%	50% to 70%
Stock Funds	40%	30% to 50%
Tactical Asset Allocation Overlay (TAA)	0%	-10% to 10%

1. Negative values represent short positions in futures contracts that may be taken using the applicable overlay strategy.

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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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.

<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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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.

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:

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 113% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to equity securities and up to 70% of its assets to fixed income securities.

The Fund's "neutral" allocation is as follows:

• 60% of the Fund's total assets in bond funds; and

• 40% of the Fund's total assets in stock funds.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a multi-asset, multi-style investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns. The Fund's broad diversification may help to reduce the overall impact of any one asset class underperforming, but may also limit upside potential. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities. We may adjust the Fund's effective allocation throughout the year.

The fixed income portion of the Fund employs a variety of investment styles, intended in the aggregate to reduce price and return volatility, and deliver more consistent returns. The Fund's fixed income portion may invest in U.S. investment grade bonds, below investment grade (high yield) bonds, inflation protected bonds, and foreign issues.

The equity portion of the Fund blends multiple investment styles in an attempt to reduce the risk associated with the use of a single style, which may move in and out of favor during the course of a market cycle. Equity holdings are diversified across U.S. large company, U.S. small company, international developed and emerging market stocks.

In addition, certain of the fixed income and equity master portfolios in which the Fund invests may employ a variety of derivative instruments such as futures, options and swap agreements. To the extent that one or more master portfolios is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

The Fund will incorporate a Tactical Asset Allocation (TAA) Overlay strategy which invests in long and/or short positions in exchange-traded futures contracts across a variety of asset classes, which include, but are not limited to, stocks, bonds, and currencies. The TAA Overlay strategy seeks to improve the Fund's risk/return profile through the tactical use of futures contracts. The TAA Overlay uses qualitative and quantitative inputs to guide equity and fixed income exposures in the Fund. Dependent upon market conditions, the TAA Overlay may increase or decrease exposures to a given asset class.

As part of managing the Fund's level of risk, both in absolute terms and relative to its benchmark, we may make changes to the allocations among investment styles at any time. We may use cash flows or effect transactions to accomplish these changes.

Portfolio Asset Allocation

The following table provides the Fund's neutral allocation and target ranges.

Asset Class	Neutral Position	Range1
Bond Funds	60%	50% to 70%
Stock Funds	40%	30% to 50%
Tactical Asset Allocation Overlay (TAA)	0%	-10% to 10%

1. Negative values represent short positions in futures contracts that may be taken using the applicable overlay strategy.

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.

Growth/Value Investing Risk. Securities that exhibit growth or value characteristics tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions.

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

Interest Rate Risk. When interest rates rise, the value of debt securities tends to fall. When interest rates decline, interest that a Fund is able to earn on its investments in debt securities may also decline, but the value of those securities may increase.

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.

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.

Effective November 30, 2017, the composition of the Growth Balanced Blended Index was changed to 35% Bloomberg Barclays U.S. Aggregate Bond Index, 45% Russell 3000® Index and 20% MSCI ACWI ex-U.S. Index. Prior to November 30, 2017 it was comprised of 35% of Bloomberg Barclays U.S. Aggregate Bond Index, 16.25% Russell 1000® Growth Index, 16.25% Russell 1000® Value Index, 16.25% S&P 500 Index, 9.75% MSCI EAFE Index (Net) and 6.50% Russell 2000® Index. You cannot invest directly in an index.

[3] The Manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund's Total Annual Fund Operating Expenses After Fee Waivers at the amount shown above. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any) from funds in which the underlying master portfolios and funds invest and from money market funds, and extraordinary expenses are excluded from the expense cap. All other acquired fund fees and expenses from the affiliated master portfolios and funds are included in the expense cap. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

[5] Historical performance shown for the Institutional Class shares prior to their inception reflects the performance of the Administrator Class shares, and is not adjusted to reflect Institutional Class expenses. If these expenses had been included, returns for Institutional Class would be higher. The Administrator Class annual returns are substantially similar to what the Institutional Class annual returns would be because the Administrator and Institutional Class shares are invested in the same portfolio and their returns differ only to the extent that they do not have the same expenses.
