(Wells Fargo WealthBuilder Funds - Institutional Class) | (Wells Fargo WealthBuilder Conservative Allocation Fund)

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

The Fund seeks current income with a secondary emphasis on 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.

<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 WealthBuilder Conservative Allocation Fund)	Institutional Class ­

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>

Management Fees	0.25%
Distribution (12b-1) Fees	none
Other Expenses	0.17%
Acquired Fund Fees and Expenses	0.41%
Total Annual Fund Operating Expenses	0.83%

Total Annual Fund Operating Expenses After Fee Waivers	0.83%	[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 WealthBuilder Conservative Allocation Fund)	1 Year	3 Years	5 Years	10 Years
Institutional Class | ­ | USD ($)	85	265	460	1,025

<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 192% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 30% of its assets to stock funds, up to 85% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 20% of the Fund's total assets in stock funds;

• 75% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings may be diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment grade bonds, inflation-protected bonds, and foreign issues. Stock holdings may be diversified across a wide range of stock fund styles including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities, foreign currency, natural resources, precious metals and other non-traditional investments, or following merger arbitrage, managed futures, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	20%	10% to 30%
Bond Funds	75%	65% to 85%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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 63% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by investing at least 80% of the Fund's net assets in equity securities (through investment in Underlying Funds). The Fund is a diversified equity investment that consists of Underlying Funds that employ different and complementary investment styles to provide potential for growth. These equity styles include large company, small company, and international. Additionally, we may invest up to 20% of the Fund's net assets in bond or alternative-style asset classes (through investment in Underlying Funds).

Depending on market conditions, some equity asset classes will perform better than others. The Fund's broad diversification across equity styles and the use of tactical allocation between equity styles may help to reduce the overall impact of poor performance in any one equity asset class.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among various Underlying Funds. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains two specific risk management components: 1.) Volatility Management Overlay (VMO) and 2.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

2. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

<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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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 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.

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.

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.

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.

<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 93% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 90% of its assets to stock funds, up to 25% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 80% of the Fund's total assets in stock funds;

• 15% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, and alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international . Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	80%	70% to 90%
Bond Funds	15%	5% to 25%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

<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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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>

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 161% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to stock funds, up to 65% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

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

• 55% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	40%	30% to 50%
Bond Funds	55%	45% to 65%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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 47 and 48 of the Prospectus and "Additional Purchase and Redemption Information" on page 54 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.

<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 192% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 30% of its assets to stock funds, up to 85% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 20% of the Fund's total assets in stock funds;

• 75% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings may be diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment grade bonds, inflation-protected bonds, and foreign issues. Stock holdings may be diversified across a wide range of stock fund styles including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities, foreign currency, natural resources, precious metals and other non-traditional investments, or following merger arbitrage, managed futures, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	20%	10% to 30%
Bond Funds	75%	65% to 85%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

<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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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>

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 63% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by investing at least 80% of the Fund's net assets in equity securities (through investment in Underlying Funds). The Fund is a diversified equity investment that consists of Underlying Funds that employ different and complementary investment styles to provide potential for growth. These equity styles include large company, small company, and international. Additionally, we may invest up to 20% of the Fund's net assets in bond or alternative-style asset classes (through investment in Underlying Funds).

Depending on market conditions, some equity asset classes will perform better than others. The Fund's broad diversification across equity styles and the use of tactical allocation between equity styles may help to reduce the overall impact of poor performance in any one equity asset class.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among various Underlying Funds. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains two specific risk management components: 1.) Volatility Management Overlay (VMO) and 2.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

2. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

<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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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 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.

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.

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

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

<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 93% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 90% of its assets to stock funds, up to 25% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 80% of the Fund's total assets in stock funds;

• 15% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, and alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international . Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

<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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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> 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 129% 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>

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 70% of its assets to stock funds, up to 45% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

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

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

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international. Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	60%	50% to 70%
Bond Funds	35%	25% to 45%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

<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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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:

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 192% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 30% of its assets to stock funds, up to 85% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 20% of the Fund's total assets in stock funds;

• 75% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings may be diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment grade bonds, inflation-protected bonds, and foreign issues. Stock holdings may be diversified across a wide range of stock fund styles including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities, foreign currency, natural resources, precious metals and other non-traditional investments, or following merger arbitrage, managed futures, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	20%	10% to 30%
Bond Funds	75%	65% to 85%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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:

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 63% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by investing at least 80% of the Fund's net assets in equity securities (through investment in Underlying Funds). The Fund is a diversified equity investment that consists of Underlying Funds that employ different and complementary investment styles to provide potential for growth. These equity styles include large company, small company, and international. Additionally, we may invest up to 20% of the Fund's net assets in bond or alternative-style asset classes (through investment in Underlying Funds).

Depending on market conditions, some equity asset classes will perform better than others. The Fund's broad diversification across equity styles and the use of tactical allocation between equity styles may help to reduce the overall impact of poor performance in any one equity asset class.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among various Underlying Funds. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains two specific risk management components: 1.) Volatility Management Overlay (VMO) and 2.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

2. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
US Large Cap Sock Funds	60%	50% to 70%
US Small Cap Stock Funds	10%	0% to 20%
International Stock Funds	30%	20% to 40%
Alternative/Bond Funds	0%	0% to 20%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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 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.

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.

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

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 90% of its assets to stock funds, up to 25% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 80% of the Fund's total assets in stock funds;

• 15% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, and alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international . Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

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

Asset Class	Neutral Position	Range1

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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:

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 129% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 70% of its assets to stock funds, up to 45% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

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

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

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international. Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	60%	50% to 70%
Bond Funds	35%	25% to 45%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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 161% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to stock funds, up to 65% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

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

• 55% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	40%	30% to 50%
Bond Funds	55%	45% to 65%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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 30% of its assets to stock funds, up to 85% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 20% of the Fund's total assets in stock funds;

• 75% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings may be diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment grade bonds, inflation-protected bonds, and foreign issues. Stock holdings may be diversified across a wide range of stock fund styles including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities, foreign currency, natural resources, precious metals and other non-traditional investments, or following merger arbitrage, managed futures, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	20%	10% to 30%
Bond Funds	75%	65% to 85%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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:

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 63% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by investing at least 80% of the Fund's net assets in equity securities (through investment in Underlying Funds). The Fund is a diversified equity investment that consists of Underlying Funds that employ different and complementary investment styles to provide potential for growth. These equity styles include large company, small company, and international. Additionally, we may invest up to 20% of the Fund's net assets in bond or alternative-style asset classes (through investment in Underlying Funds).

Depending on market conditions, some equity asset classes will perform better than others. The Fund's broad diversification across equity styles and the use of tactical allocation between equity styles may help to reduce the overall impact of poor performance in any one equity asset class.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among various Underlying Funds. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains two specific risk management components: 1.) Volatility Management Overlay (VMO) and 2.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

2. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
US Large Cap Sock Funds	60%	50% to 70%
US Small Cap Stock Funds	10%	0% to 20%
International Stock Funds	30%	20% to 40%
Alternative/Bond Funds	0%	0% to 20%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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 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.

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.

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

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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]

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 93% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 90% of its assets to stock funds, up to 25% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

• 80% of the Fund's total assets in stock funds;

• 15% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, and alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international . Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	80%	70% to 90%
Bond Funds	15%	5% to 25%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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:

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 129% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 70% of its assets to stock funds, up to 45% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

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

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

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of stock, bond, alternative investment strategy funds, with an emphasis on stocks. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international. Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	60%	50% to 70%
Bond Funds	35%	25% to 45%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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:

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 161% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a fund-of-funds that invests in various affiliated mutual funds, unaffiliated mutual funds, and exchange-traded funds ("Underlying Funds") to pursue its investment objective. We seek to achieve the Fund's investment objective by allocating up to 50% of its assets to stock funds, up to 65% of its assets to bond funds and up to 20% of its assets to alternative investment funds. The Fund's broad diversification helps to reduce the overall impact of any one asset class underperforming, but may also limit upside potential.

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

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

• 55% of the Fund's total assets in bond funds; and

• 5% of the Fund's total assets in alternative investment funds.

We may adjust the Fund's target allocation throughout the year.

The Fund is a diversified portfolio of bond, stock and alternative investment strategy funds, with an emphasis on bonds. Bond holdings are diversified across a wide range of bond fund styles that consist of short- to long-term income-producing securities, including U.S. Government obligations, corporate bonds, below investment- grade bonds, inflation-protected bonds, and foreign issues. Stock holdings are diversified across a wide range of stock fund styles, including large company, small company and international. Alternative investment holdings are allocated across funds that use alternative investment strategies, which may include, but are not limited to, investing in or having exposure to commodities, real estate, foreign currency, natural resources, precious metals and other non-traditional investments, or following managed futures, merger arbitrage, global multi-asset, long-short, market neutral, or other tactical investment strategies. An Underlying Fund that is considered an "alternative investment fund" may hold equity and/or fixed income securities as part of its underlying portfolio holdings. We consider the Underlying Fund's overall strategy in determining whether it is an "alternative investment fund" for purposes of making investments consistent with the Fund's target allocation.

We employ both quantitative analysis and qualitative judgments in making tactical allocations among asset classes. Quantitative analysis involves the use of proprietary asset allocation models, which employ various valuation techniques. Qualitative judgments are made based on assessments of a number of factors, including economic conditions, corporate earnings, monetary policy, market valuations, investor sentiment, and market technicals. Changes to effective allocations in the Fund may be implemented with index futures contracts or by buying and selling Underlying Funds, or both.

The Fund will incorporate a futures overlay strategy that contains three specific risk management components: 1.) Tactical Asset Allocation (TAA) Overlay, 2.) Volatility Management Overlay (VMO), and 3.) Put Replication Overlay (PRO). Together these strategies will allow the Fund to attempt to manage short-term volatility, mitigate risk and/or improve returns under certain market conditions. To execute this overlay strategy, the Fund 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.

1. The Tactical Asset Allocation (TAA) Overlay 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.

2. The Volatility Management Overlay (VMO) seeks to keep the Fund's short-term volatility in-line with its strategic long-term target. The VMO uses quantitative inputs and strives to decrease the portfolio's effective equity exposure when projected equity market volatility is higher than average, and increasing the portfolio's effective equity exposure when projected equity market volatility is lower than average. The VMO may increase exposures to a given asset class under certain market conditions while decreasing exposure during others.

3. The Put Replication Overlay (PRO) is a quantitatively driven, structured hedging component designed to buffer the Fund against portfolio losses. Although executed using futures contracts, this component is designed substantially to replicate the payout structure of a theoretical protective put option on a given portfolio. The PRO will only seek to decrease market exposure under certain market conditions.

Portfolio Asset Allocation

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

Asset Class	Neutral Position	Range1
Stock Funds	40%	30% to 50%
Bond Funds	55%	45% to 65%
Alternative Investment Funds	5%	5% to 20%
Tactical Asset Allocation Overlay	0%	-10% to 10%
Volatility Management Overlay	0%	-5% to 5%
Put Replication Overlay	0%	-60% to 0%

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.

Alternative Investment Risk. Alternative investment strategies, which may include, but are not limited to, investing in or having exposure to real estate, commodities (including precious metals), foreign currency, natural resources and other non-traditional investments, or following managed futures, event driven, global multi-asset, long-short, market neutral or other tactical investment strategies, may involve complex securities types or transactions and extensive short positions and/or focus on narrow segments of the market, which may increase and/or magnify the overall risks and volatility associated with the strategies.

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.

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.

Underlying Funds Risk. The risks associated with a Fund include the risks related to each Underlying Fund in which the Fund invests.

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 Class A annual returns are substantially similar to what the Institutional Class annual returns would be because the Institutional Class and Class A shares are invested in the same portfolio and their returns differ only to the extent that they do not have the same expenses or sales loads.

[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 0.42% for Institutional Class. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from 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.

[4] Historical performance for Class A shares prior to their inception reflects the performance of Class C shares and includes the higher expenses applicable to Class C shares. If these expenses had not been included, returns for Class A shares would be higher. Prior to February 13, 2017, historical performance shown for Class C shares reflects the performance of the Fund's predecessor WealthBuilder Portfolio share class and does not reflect the front-end sales load previously attributable to the predecessor class. The expenses for Class C shares and the predecessor share class are similar.

[5] Investments of $1 million or more are not subject to a front-end sales charge but generally will be subject to a deferred sales charge of 1.00% if redeemed within 18 months from the date of purchase.

[6] The expense ratio shown does not correlate to the corresponding expense ratio shown in the Financial Highlights, which reflects only the operating expenses of the Fund and does not include any acquired fund fees and expenses.

[7] 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 0.75% for Class A, and 1.50% for Class C. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any), and extraordinary expenses are excluded from 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.
