(WFA Target Date Retirement Funds - Classes A and C) | (Wells Fargo Target Today Fund)

Investment Objective

The Fund seeks total return over time, consistent with its strategic target asset allocation.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. 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 88 and 89 of the Prospectus and "Additional Purchase and Redemption Information" on page 62 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 122 for further information.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - ­ - (Wells Fargo Target Today Fund)	Class A		Class C
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	5.75%		none
Maximum deferred sales charge (load) (as a percentage of offering price)	none	[1]	1.00%

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

^[1]

Annual Fund Operating Expenses - ­ - (Wells Fargo Target Today Fund)		Class A	Class C
Management Fees		0.10%	0.10%
Distribution (12b-1) Fees		none	0.75%
Other Expenses		0.56%	0.56%
Acquired Fund Fees and Expenses		0.15%	0.15%
Total Annual Fund Operating Expenses		0.81%	1.56%
Fee Waivers		(0.16%)	(0.16%)
Total Annual Fund Operating Expenses After Fee Waiver	[1]	0.65%	1.40%

Example of Expenses

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

Assuming Redemption at End of Period

Expense Example - (Wells Fargo Target Today Fund) - ­ - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	638	804	984	1,505
Class C	243	477	835	1,843

Assuming No Redemption

Expense Example, No Redemption - (Wells Fargo Target Today Fund)	1 Year	3 Years	5 Years	10 Years
Class C | ­ | USD ($)	143	477	835	1,843

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	14.3%
Wells Fargo Factor Enhanced International Portfolio	7.4%
Wells Fargo Factor Enhanced Small Cap Portfolio	3.6%
Wells Fargo U.S. REIT Portfolio	2.5%
Wells Fargo Factor Enhanced Emerging Markets Portfolio	2.2%
Fixed Income Securities
Wells Fargo Bloomberg Barclays U.S. Aggregate ex-Corp Portfolio	34.5%
Wells Fargo Investment Grade Corporate Bond Portfolio	17.9%
Wells Fargo Strategic Retirement Bond Portfolio (includes both TIPs & Intermediate Government Bond allocations)	11.7%
Wells Fargo Emerging Markets Bond Portfolio	2.9%
Wells Fargo High Yield Corporate Bond Portfolio	2.9%

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Class C | ­ | USD ($)	143	479	839	1,853

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 79% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

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.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. 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 88 and 89 of the Prospectus and "Additional Purchase and Redemption Information" on page 62 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 122 for further information.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2015 Fund)	1 Year	3 Years	5 Years	10 Years
Class A | ­ | USD ($)	638	806	988	1,515

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 76% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2015 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. 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 88 and 89 of the Prospectus and "Additional Purchase and Redemption Information" on page 62 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 122 for further information.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2025 Fund)	1 Year	3 Years	5 Years	10 Years
Class A | ­ | USD ($)	638	796	967	1,464

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 67% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 61% of the average value of its portfolio.

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.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Investment Objective

The Fund seeks total return over time, consistent with its strategic target asset allocation.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. 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 88 and 89 of the Prospectus and "Additional Purchase and Redemption Information" on page 62 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 122 for further information.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - (Wells Fargo Target 2035 Fund)	Class A ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	5.75%
Maximum deferred sales charge (load) (as a percentage of offering price)	none	[1]

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Example of Expenses

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

Expense Example - (Wells Fargo Target 2035 Fund)	1 Year	3 Years	5 Years	10 Years
Class A | ­ | USD ($)	638	800	976	1,484

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Investment Objective

The Fund seeks total return over time, consistent with its strategic target asset allocation.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. 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 88 and 89 of the Prospectus and "Additional Purchase and Redemption Information" on page 62 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 122 for further information.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - (Wells Fargo Target 2045 Fund)	Class A ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	5.75%
Maximum deferred sales charge (load) (as a percentage of offering price)	none	[1]

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Example of Expenses

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

Expense Example - (Wells Fargo Target 2045 Fund)	1 Year	3 Years	5 Years	10 Years
Class A | ­ | USD ($)	638	806	988	1,515

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 46% of the average value of its portfolio.

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.

Investment Objective

The Fund seeks total return over time, consistent with its strategic target asset allocation.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. 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 88 and 89 of the Prospectus and "Additional Purchase and Redemption Information" on page 62 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 122 for further information.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2055 Fund)	1 Year	3 Years	5 Years	10 Years
Class A | ­ | USD ($)	638	840	1,059	1,689

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2055. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2055 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 46% of the average value of its portfolio.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target Today Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	55	214	387	889

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	14.3%
Wells Fargo Factor Enhanced International Portfolio	7.4%
Wells Fargo Factor Enhanced Small Cap Portfolio	3.6%
Wells Fargo U.S. REIT Portfolio	2.5%
Wells Fargo Factor Enhanced Emerging Markets Portfolio	2.2%
Fixed Income Securities
Wells Fargo Bloomberg Barclays U.S. Aggregate ex-Corp Portfolio	34.5%
Wells Fargo Investment Grade Corporate Bond Portfolio	17.9%
Wells Fargo Strategic Retirement Bond Portfolio (includes both TIPs & Intermediate Government Bond allocations)	11.7%
Wells Fargo Emerging Markets Bond Portfolio	2.9%
Wells Fargo High Yield Corporate Bond Portfolio	2.9%

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 79% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2015 Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	55	216	392	900

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 76% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015.

The Fund's target year of 2020 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2025 Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	55	206	369	844

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 67% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2035 Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	55	210	378	867

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

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.

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 51% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility.

Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 46% of the average value of its portfolio.

The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2055. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2055 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Fees and Expenses

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - (Wells Fargo Target 2060 Fund)	Administrator Class ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of offering price)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Total Annual Fund Operating Expenses After Fee Waiver	0.54%	[1]

Example of Expenses

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

Expense Example - (Wells Fargo Target 2060 Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	55	397	762	1,790

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2060. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target Today Fund)	1 Year	3 Years	5 Years	10 Years
Class R | ­ | USD ($)	92	321	569	1,280

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

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

Expense Example - (Wells Fargo Target 2010 Fund)	1 Year	3 Years	5 Years	10 Years
Class R | ­ | USD ($)	92	323	574	1,290

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 79% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2015 Fund)	1 Year	3 Years	5 Years	10 Years

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 76% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2015 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 67% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 61% of the average value of its portfolio.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2040 Fund)	1 Year	3 Years	5 Years	10 Years
Class R | ­ | USD ($)	92	313	552	1,237

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 51% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2050 Fund)	1 Year	3 Years	5 Years	10 Years

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target Today Fund)	1 Year	3 Years	5 Years	10 Years
Class R4 | ­ | USD ($)	35	151	277	647

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2010 Fund)	1 Year	3 Years	5 Years	10 Years
Class R4 | ­ | USD ($)	35	153	282	658

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 79% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2020 Fund)	1 Year	3 Years	5 Years	10 Years
Class R4 | ­ | USD ($)	35	140	255	590

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 73% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2020. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2020 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 67% of the average value of its portfolio.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 61% of the average value of its portfolio.

The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2030. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2030 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2035 Fund)	1 Year	3 Years	5 Years	10 Years
Class R4 | ­ | USD ($)	35	146	268	624

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2045 Fund)	1 Year	3 Years	5 Years	10 Years
Class R4 | ­ | USD ($)	35	153	282	658

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2055. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2055 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund seeks total return over time, consistent with its strategic target asset allocation.

Fees and Expenses

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - (Wells Fargo Target 2060 Fund)	Class R4 ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of offering price)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

^[1]

Annual Fund Operating Expenses - (Wells Fargo Target 2060 Fund)	Class R4 ­
Management Fees	0.10%
Distribution (12b-1) Fees	none
Other Expenses	1.09%
Acquired Fund Fees and Expenses	0.19%
Total Annual Fund Operating Expenses	1.38%
Fee Waivers	(1.04%)
Total Annual Fund Operating Expenses After Fee Waiver	0.34%	[1]

Example of Expenses

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

Expense Example - (Wells Fargo Target 2060 Fund)	1 Year	3 Years	5 Years	10 Years
Class R4 | ­ | USD ($)	35	334	656	1,567

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets.

Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 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 Target 2010 Fund)	1 Year	3 Years	5 Years	10 Years
Class R6 | ­ | USD ($)	19	105	199	473

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 79% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2015 Fund)	1 Year	3 Years	5 Years	10 Years
Class R6 | ­ | USD ($)	19	105	199	473

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 76% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2015 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 67% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2030 Fund)	1 Year	3 Years	5 Years	10 Years
Class R6 | ­ | USD ($)	19	92	171	404

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 61% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Example of Expenses

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

Expense Example - (Wells Fargo Target 2040 Fund)	1 Year	3 Years	5 Years	10 Years
Class R6 | ­ | USD ($)	19	94	176	416

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 51% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Example of Expenses

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

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 79% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	15.7%

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 76% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2015 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	18.1%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 73% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2020. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2020 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 67% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2030. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2030 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 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 51% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 48% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	42.4%
Wells Fargo Factor Enhanced International Portfolio	27.0%
Wells Fargo Factor Enhanced Small Cap Portfolio	10.6%

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 46% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2060. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	14.3%
Wells Fargo Factor Enhanced International Portfolio	7.4%
Wells Fargo Factor Enhanced Small Cap Portfolio	3.6%
Wells Fargo U.S. REIT Portfolio	2.5%
Wells Fargo Factor Enhanced Emerging Markets Portfolio	2.2%
Fixed Income Securities
Wells Fargo Bloomberg Barclays U.S. Aggregate ex-Corp Portfolio	34.5%
Wells Fargo Investment Grade Corporate Bond Portfolio	17.9%
Wells Fargo Strategic Retirement Bond Portfolio (includes both TIPs & Intermediate Government Bond allocations)	11.7%

Wells Fargo High Yield Corporate Bond Portfolio	2.9%

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 73% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2020. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2020 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	22.2%
Wells Fargo Factor Enhanced International Portfolio	11.8%

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 67% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	27.6%
Wells Fargo Factor Enhanced International Portfolio	15.3%
Wells Fargo Factor Enhanced Small Cap Portfolio	6.9%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2030. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2030 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

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

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 51% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	40.3%
Wells Fargo Factor Enhanced International Portfolio	25.1%
Wells Fargo Factor Enhanced Small Cap Portfolio	10.1%
Wells Fargo Factor Enhanced Emerging Markets Portfolio	7.5%

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 46% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2055. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2055 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	43.2%
Wells Fargo Factor Enhanced International Portfolio	27.7%

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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

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 46% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2060. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 79% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

During the most recent fiscal year, the Fund's portfolio turnover rate was 76% of the average value of its portfolio.

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2015 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 67% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

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 61% of the average value of its portfolio.

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2030. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2030 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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.

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.

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 51% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2055. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2055 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 80% of the average value of its portfolio.

Strategy [Heading]

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	14.3%
Wells Fargo Factor Enhanced International Portfolio	7.4%
Wells Fargo Factor Enhanced Small Cap Portfolio	3.6%
Wells Fargo U.S. REIT Portfolio	2.5%
Wells Fargo Factor Enhanced Emerging Markets Portfolio	2.2%
Fixed Income Securities
Wells Fargo Bloomberg Barclays U.S. Aggregate ex-Corp Portfolio	34.5%
Wells Fargo Investment Grade Corporate Bond Portfolio	17.9%
Wells Fargo Strategic Retirement Bond Portfolio (includes both TIPs & Intermediate Government Bond allocations)	11.7%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Strategy Narrative [Text Block]

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market.

The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate.

The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

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 73% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2020. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2020 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	22.2%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2025 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues.

The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2030. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance.

Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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.

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 55% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 equity Underlying Funds are each intended to provide exposure to a specific market segment.

The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology.

The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

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

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2060. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to the following asset classes: equity and fixed income (including money market securities). The Fund's investment strategy is to diversify the Fund's investments among these asset classes.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The large- and small-cap companies, international developed markets and emerging markets allocations are designed to track (replicate the performance of) indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The "Today" designation in the Fund's name is meant to indicate that the Fund is primarily designed for investors either in retirement and/or currently gradually withdrawing funds from their investments. The Fund does not decrease its equity holdings in an attempt to become increasingly conservative over time, but rather maintains a strategic target allocation to equity and fixed income securities (including money market instruments) in the weights of 30% and 70%, respectively.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

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

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2010. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2010 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	15.7%

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

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

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors who retired and/or began to gradually withdraw funds around its target date of 2015. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2015 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	18.1%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2020. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2020 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

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

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2025. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, international (non-U.S.) developed and emerging markets, and real estate. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index. The real estate allocation invests in real estate investment trusts (REITs) and is managed to replicate the performance of the Wells Fargo US REIT Index, a traditional market-capitalization weighted index designed to provide diversified exposure to real estate. The Wells Fargo US REIT Index rebalances quarterly.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations (including Treasury inflation-protected securities, or TIPS), investment grade corporate bonds, below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. bond sectors (including mortgage- and asset-backed securities), and emerging markets foreign issues. The inflation-protected Treasury and intermediate-term government allocations, will be managed to replicate the performance of the Bloomberg Barclays US Treasury Inflation-Linked 1-10 Year Bond Index and the Bloomberg Barclays US Government Intermediate Bond Index, respectively, each a traditional market-capitalization weighted index designed to provide diversified exposure to their respective allocation. Each index rebalances monthly. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2030. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2030 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	32.7%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

Real Estate Securities Risk. Investments in real estate securities are subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries. Factors affecting real estate values include the supply of real property in particular markets, overbuilding, changes in zoning laws, casualty or condemnation losses, delays in completion of construction, changes in real estate values, changes in operations costs and property taxes, levels of occupancy, adequacy of rent to cover operating costs, possible environmental liabilities, regulatory limitations on rent, fluctuations in rental income, increased competition and other risks related to local and regional market conditions. The value of real-estate related investments also may be affected by changes in interest rates, macroeconomic developments, and social and economic trends. For instance, during periods of declining interest rates, certain REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may reduce the yield on securities issued by those REITs. Some REITs have relatively small market capitalizations, which can tend to increase the volatility of the market price of their securities. REITs are subject to the risk of fluctuations in income from underlying real estate assets, their inability to manage effectively the cash flows generated by those assets, prepayments and defaults by borrowers, and their failure to qualify for the special tax treatment granted to REITs under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from investment company status under the 1940 Act.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.

Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2035. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2035 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 51% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2040. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2040 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2045. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2045 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes.

The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2050. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2050 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

U.S. Government Obligations Risk. U.S. Government obligations may be adversely impacted by changes in interest rates, and securities issued or guaranteed by U.S. Government agencies or government-sponsored entities may not be backed by the full faith and credit of the U.S. Government.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a gateway fund that invests in various master portfolios ("Underlying Funds"), which in turn, invest in a combination of securities to gain exposure to equity and fixed income asset classes. The Fund gradually reduces its potential market risk exposures over time by generally re-allocating its assets among these asset classes, consistent with increasingly conservative strategic target allocations.

The equity Underlying Funds are each intended to provide exposure to a specific market segment. Those segments include U.S. large- and small-capitalization companies, and international (non-U.S.) developed and emerging markets. The U.S. large- and small-cap companies, international developed markets and emerging markets allocations are designed to replicate the performance of indexes created with a proprietary methodology. This methodology is designed to provide exposure to specific factors (or characteristics) that are commonly tied to a stock's potential for enhanced risk-adjusted returns relative to the market. Those factors include, but are not limited to value, quality, momentum, small size, and low volatility. The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2055. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2055 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Portfolio Asset Allocation

The following table provides the Fund's target allocations to various underlying portfolios as of its most recent fiscal year end.

Portfolio	Target Allocation
Equity Securities
Wells Fargo Factor Enhanced Large Cap Portfolio	43.2%

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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 equity Underlying Funds are each intended to provide exposure to a specific market segment.

The process to construct each index begins with a reference index universe and systematically excludes constituents based on their expected contribution to projected risk and return of that overall universe. Each constituent's expected contribution to the overall risk and return of the universe is a function of that constituent's factor exposures and the volatility of each factor. The U.S. large-company and small-cap company indexes are expected to rebalance semi-annually, while the international developed and emerging market indexes are expected to rebalance on a quarterly basis. The large-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Large Cap Index. The small-cap company allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Small Cap Index. The developed international allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced International Index. The emerging markets allocation will be managed to replicate the performance of the Wells Fargo Factor Enhanced Emerging Market Index.

The fixed income Underlying Funds provide diversified exposure across a wide range of market sectors, including U.S. Government obligations, corporate investment grade and below investment grade bonds (commonly known as "high yield bonds" or "junk bonds"), other U.S. aggregate bond sectors (including mortgage- and asset-backed securities), and emerging market foreign issues. The investment grade corporate bond and below investment grade corporate bond allocations will be managed to replicate the performance of indexes created with a proprietary index methodology. The methodology is designed to provide broadly diversified fixed income exposure and is constructed to enhance issuer diversification and liquidity versus other standard traditional passive bond indexes. Specifically, the indexes first reweight the reference index universe of securities to limit concentration in the largest issuers and remove lower liquidity securities. They then reweight across size groupings to better align the yield and duration characteristics of the index with the original reference index, while at the same time maintaining the greater diversification and increased liquidity achieved through the prior step. The indexes rebalance monthly. The investment grade corporate bond allocation will be managed to replicate the performance of the Wells Fargo U.S. Investment Grade Corporate Bond Index. The below investment grade bond allocation will be managed to replicate the performance of the Wells Fargo U.S. High Yield Bond Index. The U.S. aggregate bond ex-corporate allocation, which includes mortgage- and asset-backed securities, will be managed to replicate the performance of the Bloomberg Barclays US Aggregate ex-Corporate Index, a traditional market-capitalization weighted index designed to provide diversified exposure to the allocation. The index rebalances monthly. The emerging markets bond allocation will be managed to replicate the performance of the JP Morgan EMBI Global Diversified Index, an index that deviates from a traditional market capitalization weighting to provide more robust diversification across its constituent countries; the index rebalances monthly.

The Fund is primarily designed for investors expecting to retire and/or begin gradually withdrawing funds around its target date of 2060. As the Fund's time horizon to its target date shortens, it generally replaces some of its equity holdings with fixed income holdings in an attempt to reduce market risk and thereby become more conservative in its asset allocation. This reallocation occurs according to a predetermined "glide path," which was developed based on long-term capital market return expectations, actuarial assumptions about life expectancy and retirement, and assumptions about investors' risk tolerance. The reallocation continues as the Fund's target year approaches and for the first ten years afterward. The Fund's target year of 2060 serves as a guide to the risk profile of the Fund, and your decision to invest in a Wells Fargo Target Date Fund with a particular target year and risk profile depends on your individual risk tolerance, among other factors.

The Fund will not reach its lowest strategic target allocation to equities until ten years past the Fund's target year. During the ten-year period after the Fund's target year, the Fund's asset allocation will increasingly resemble that of the Target Today Fund and at the end of the ten-year period, we will likely combine it with the Target Today Fund.

While the Fund invests exclusively in Underlying Funds that track an index, the Fund does not track a published index. At their discretion, the Fund's portfolio managers may make changes to the Fund's glide path and asset allocation consistent with the Fund's target year. Factors that the portfolio managers may consider include but are not limited to market trends, their outlook for a given market capitalization, and the Underlying Funds' performance in various market conditions.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Credit Risk. The issuer or guarantor of a debt security may be unable or perceived to be unable to pay interest or repay principal when they become due, which could cause the value of an investment to decline and a Fund to lose money.

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.

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

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

Management Risk. Investment decisions, techniques, analyses or models implemented by a Fund's manager or sub-adviser in seeking to achieve the Fund's investment objective may not produce the returns expected, may cause the Fund's shares to lose value or may cause the Fund to underperform other funds with similar investment objectives.

Market Risk. The values of, and/or the income generated by, securities held by a Fund may decline due to general market conditions or other factors, including those directly involving the issuers of such securities. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments.

Mortgage- and Asset-Backed Securities Risk. Mortgage- and asset-backed securities may decline in value and become less liquid when defaults on the underlying mortgages or assets occur and may exhibit additional volatility in periods of rising interest rates. Rising interest rates tend to extend the duration of these securities, making them more sensitive to changes in interest rates than instruments with fixed payment schedules. When interest rates decline or are low, the prepayment of mortgages or assets underlying such securities can reduce a Fund's returns.

New Fund Risk. The Fund is a new fund, with a limited or no operating history and a small asset base. There can be no assurance that the Fund will grow to or maintain a viable size. Due to the Fund's small asset base, certain of the Fund's expenses and its portfolio transaction costs may be higher than those of a fund with a larger asset base. To the extent that the Fund does not grow to or maintain a viable size, it may be liquidated, and the expenses, timing and tax consequences of such liquidation may not be favorable to some shareholders.

Regulatory Risk. Pursuant to section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and certain rules promulgated thereunder (collectively known as the "Volcker Rule"), if the Manager and/or its affiliates own 25% or more of the outstanding shares of the Fund more than three years after the Fund's inception date (or such longer period as may be permitted by the Federal Reserve), the Fund will be subject to restrictions on trading that will adversely impact the Fund's ability to execute its investment strategy. Should this occur, the Fund may decide to liquidate, or the Manager and/or its affiliates may be required to reduce their ownership interests in the Fund, either of which may result in gains or losses, increased transaction costs and adverse tax consequences.

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

Target Date Fund Risk. A Target Date Fund cannot provide assurance that an investor's investment in the Fund will provide income at, and through the years following, the target year in the Fund's name in amounts adequate to meet the investor's financial goals. In addition, the Fund is subject to the risk that its strategy will not eliminate investment volatility that could reduce the amount of funds available for an investor who begins to withdraw funds or expects to retire close to or in the Fund's target year.

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.
