(WFA US Equity Funds - Administrator Class) | (Wells Fargo C&B Large Cap Value Fund)

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

The Fund seeks maximum long-term total return (current income and capital appreciation), consistent with minimizing risk to principal.

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

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

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

Shareholder Fees - (Wells Fargo C&B Large Cap Value Fund)	Administrator Class ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of offering price)	none

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

Annual Fund Operating Expenses - (Wells Fargo C&B Large Cap Value Fund)	Administrator Class ­
Management Fees	0.70%	[1]
Distribution (12b-1) Fees	none
Other Expenses	0.43%
Total Annual Fund Operating Expenses	1.13%	[2]
Fee Waivers	(0.13%)
Total Annual Fund Operating Expenses After Fee Waivers	1.00%	[3]

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

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

Expense Example - (Wells Fargo C&B Large Cap Value Fund)	1 Year	3 Years	5 Years	10 Years
Administrator Class | ­ | USD ($)	102	346	610	1,363

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 42% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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

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

Focused Portfolio Risk. Changes in the value of a small number of issuers are likely to have a larger impact on a Fund's net asset value than if the Fund held a greater number of issuers.

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

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

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

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

The following information provides some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. The Fund's average annual total returns are compared to the performance of one or more indices. Past performance before and after taxes is no guarantee of future results. Current month-end performance is available on the Fund's website at wellsfargofunds.com.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state, local or foreign taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) Plans or Individual Retirement Accounts.

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 70% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a "multi-style" equity investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns.The Fund seeks broad diversification across global equity markets and investment styles within those markets, including U.S. and non-U.S. markets, large and small companies, and growth and value investment styles. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities.

We consider the Fund's absolute level of risk, and its risk relative to its benchmark in determining the allocation among the different asset classes and investment styles. We may make changes to the allocations at any time in response to market and other conditions. We may use cash flows or effect transactions to re-establish the allocations. In addition, certain of the affiliated mutual funds in which the Fund may invest may employ a variety of derivative instruments such as futures and options. To the extent that one or more affiliated mutual funds is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

Portfolio Asset Allocation

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

Asset Classes	Neutral Position	Range
US Large Cap Stock Funds	75%	65% to 85%
US Small Cap Stock Funds	10%	0% to 20%
International Stock Funds	15%	5% to 25%

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

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

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

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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

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

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

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

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

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 47% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

Different sectors of the market and different security types may react differently to such developments.

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 3% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in a diversified portfolio of equity securities designed to replicate the holdings and weightings of the stocks comprising the S&P 500 Index.

The Fund is a gateway fund that invests substantially all of its assets in the Index Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We invest in substantially all of the common stocks comprising the S&P 500 Index and attempt to achieve at least a 95% correlation between the performance of the S&P 500 Index and the Fund's investment results, before fees and expenses. This correlation is sought regardless of market conditions. If we are unable to achieve this correlation, then we will closely monitor the performance and composition of the S&P 500 Index and adjust the Fund's securities holdings as necessary to seek the correlation.

A precise duplication of the performance of the S&P 500 Index would mean that the net asset value ("NAV") of Fund shares, including dividends and capital gains, would increase or decrease in exact proportion to changes in the S&P 500 Index. Such a 100% correlation is not feasible. Our ability to track the performance of the S&P 500 Index may be affected by, among other things, transaction costs and shareholder purchases and redemptions. We continuously monitor the performance and composition of the S&P 500 Index and adjust the Fund's portfolio as necessary to reflect any changes to the S&P 500 Index and to maintain a 95% or better performance correlation before fees and expenses. Furthermore, we may use futures to manage risk or to enhance return.

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

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

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

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently.

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

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

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

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

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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 42% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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

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

Focused Portfolio Risk. Changes in the value of a small number of issuers are likely to have a larger impact on a Fund's net asset value than if the Fund held a greater number of issuers.

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

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

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

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.

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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.

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

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

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

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

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

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 42% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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

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

Focused Portfolio Risk. Changes in the value of a small number of issuers are likely to have a larger impact on a Fund's net asset value than if the Fund held a greater number of issuers.

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

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

Market Risk.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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.

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 144% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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

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

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

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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.

Focused Portfolio Risk. Changes in the value of a small number of issuers are likely to have a larger impact on a Fund's net asset value than if the Fund held a greater number of issuers.

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a "multi-style" equity investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns.The Fund seeks broad diversification across global equity markets and investment styles within those markets, including U.S. and non-U.S. markets, large and small companies, and growth and value investment styles. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities.

We consider the Fund's absolute level of risk, and its risk relative to its benchmark in determining the allocation among the different asset classes and investment styles. We may make changes to the allocations at any time in response to market and other conditions. We may use cash flows or effect transactions to re-establish the allocations. In addition, certain of the affiliated mutual funds in which the Fund may invest may employ a variety of derivative instruments such as futures and options. To the extent that one or more affiliated mutual funds is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

Portfolio Asset Allocation

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

Asset Classes	Neutral Position	Range
US Large Cap Stock Funds	75%	65% to 85%
US Small Cap Stock Funds	10%	0% to 20%
International Stock Funds	15%	5% to 25%

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

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

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

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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

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

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

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

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

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.

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 47% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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

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

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.

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

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in a diversified portfolio of equity securities designed to replicate the holdings and weightings of the stocks comprising the S&P 500 Index.

The Fund is a gateway fund that invests substantially all of its assets in the Index Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We invest in substantially all of the common stocks comprising the S&P 500 Index and attempt to achieve at least a 95% correlation between the performance of the S&P 500 Index and the Fund's investment results, before fees and expenses. This correlation is sought regardless of market conditions. If we are unable to achieve this correlation, then we will closely monitor the performance and composition of the S&P 500 Index and adjust the Fund's securities holdings as necessary to seek the correlation.

A precise duplication of the performance of the S&P 500 Index would mean that the net asset value ("NAV") of Fund shares, including dividends and capital gains, would increase or decrease in exact proportion to changes in the S&P 500 Index. Such a 100% correlation is not feasible. Our ability to track the performance of the S&P 500 Index may be affected by, among other things, transaction costs and shareholder purchases and redemptions. We continuously monitor the performance and composition of the S&P 500 Index and adjust the Fund's portfolio as necessary to reflect any changes to the S&P 500 Index and to maintain a 95% or better performance correlation before fees and expenses. Furthermore, we may use futures to manage risk or to enhance return.

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

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

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

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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.

The Fund is a gateway fund that invests substantially all of its assets in the Small Company Growth Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently.

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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 Small Company Value Fund) - ­ - USD ($)	1 Year	3 Years	5 Years	10 Years

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

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 144% of the average value of its portfolio.

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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

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

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

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

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

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

Strategy Narrative [Text Block]

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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 70% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a "multi-style" equity investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns.The Fund seeks broad diversification across global equity markets and investment styles within those markets, including U.S. and non-U.S. markets, large and small companies, and growth and value investment styles. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities.

We consider the Fund's absolute level of risk, and its risk relative to its benchmark in determining the allocation among the different asset classes and investment styles. We may make changes to the allocations at any time in response to market and other conditions. We may use cash flows or effect transactions to re-establish the allocations. In addition, certain of the affiliated mutual funds in which the Fund may invest may employ a variety of derivative instruments such as futures and options. To the extent that one or more affiliated mutual funds is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

Portfolio Asset Allocation

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

Asset Classes	Neutral Position	Range
US Large Cap Stock Funds	75%	65% to 85%
US Small Cap Stock Funds	10%	0% to 20%
International Stock Funds	15%	5% to 25%

Risk [Heading]

rr_RiskHeading

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

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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

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

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

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

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

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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.

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.

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

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

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

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

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 3% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in a diversified portfolio of equity securities designed to replicate the holdings and weightings of the stocks comprising the S&P 500 Index.

The Fund is a gateway fund that invests substantially all of its assets in the Index Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We invest in substantially all of the common stocks comprising the S&P 500 Index and attempt to achieve at least a 95% correlation between the performance of the S&P 500 Index and the Fund's investment results, before fees and expenses. This correlation is sought regardless of market conditions. If we are unable to achieve this correlation, then we will closely monitor the performance and composition of the S&P 500 Index and adjust the Fund's securities holdings as necessary to seek the correlation.

A precise duplication of the performance of the S&P 500 Index would mean that the net asset value ("NAV") of Fund shares, including dividends and capital gains, would increase or decrease in exact proportion to changes in the S&P 500 Index. Such a 100% correlation is not feasible. Our ability to track the performance of the S&P 500 Index may be affected by, among other things, transaction costs and shareholder purchases and redemptions. We continuously monitor the performance and composition of the S&P 500 Index and adjust the Fund's portfolio as necessary to reflect any changes to the S&P 500 Index and to maintain a 95% or better performance correlation before fees and expenses. Furthermore, we may use futures to manage risk or to enhance return.

Risk [Heading]

rr_RiskHeading

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

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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.

Strategy Narrative [Text Block]

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently.

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

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

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

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

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 144% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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.

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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.

Focused Portfolio Risk. Changes in the value of a small number of issuers are likely to have a larger impact on a Fund's net asset value than if the Fund held a greater number of issuers.

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

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 47% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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.

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.

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

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

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

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

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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 144% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

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

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

Strategy Narrative [Text Block]

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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.

Focused Portfolio Risk. Changes in the value of a small number of issuers are likely to have a larger impact on a Fund's net asset value than if the Fund held a greater number of issuers.

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

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 47% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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.

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.

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

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

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

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

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 144% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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.

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of large-capitalization companies.

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

We invest principally in equity securities of large-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 1000® Index at the time of purchase. The market capitalization range of the Russell 1000® Index was approximately $573 million to $1.1 trillion, as of August 31, 2018, and is expected to change frequently. We manage a relatively focused portfolio of 30 to 50 companies that enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

We select securities for the portfolio based on an analysis of a company's financial characteristics and an assessment of the quality of a company's management. In selecting a company, we consider criteria such as return on equity, balance sheet strength, industry leadership position and cash flow projections. We further narrow the universe of acceptable investments by undertaking intensive research including interviews with a company's top management, customers and suppliers. We believe our assessment of business quality and emphasis on valuation will protect the portfolio's assets in down markets, while our insistence on strength in leadership, financial condition and cash flow position will produce competitive results in all but the most speculative markets. We regularly review the investments of the portfolio and may sell a portfolio holding when it has achieved its valuation target, there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

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 70% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities.

The Fund is a fund-of-funds that invests in various affiliated mutual funds employing a "multi-style" equity investment approach designed to reduce the price and return volatility of the Fund and to provide more consistent returns.The Fund seeks broad diversification across global equity markets and investment styles within those markets, including U.S. and non-U.S. markets, large and small companies, and growth and value investment styles. The Fund may invest in Wells Fargo Master Portfolios, in other Wells Fargo Funds, or directly in securities.

We consider the Fund's absolute level of risk, and its risk relative to its benchmark in determining the allocation among the different asset classes and investment styles. We may make changes to the allocations at any time in response to market and other conditions. We may use cash flows or effect transactions to re-establish the allocations. In addition, certain of the affiliated mutual funds in which the Fund may invest may employ a variety of derivative instruments such as futures and options. To the extent that one or more affiliated mutual funds is invested in such derivatives, the Fund will be exposed to the risks associated with such investments.

Portfolio Asset Allocation

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

Asset Classes	Neutral Position	Range
US Large Cap Stock Funds	75%	65% to 85%
US Small Cap Stock Funds	10%	0% to 20%
International Stock Funds	15%	5% to 25%

Risk [Heading]

rr_RiskHeading

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

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

Foreign Investment Risk. Foreign investments may be subject to lower liquidity, greater price volatility and risks related to adverse political, regulatory, market or economic developments. Foreign investments may involve exposure to changes in foreign currency exchange rates and may be subject to higher withholding and other taxes.

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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

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

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

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

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

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's total assets in equity securities of small-capitalization companies; and

• up to 25% of the Fund's total assets in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently. Small-capitalization companies may include both domestic and foreign small-capitalization companies.

We seek small-capitalization companies that are in the emerging phase of their life cycle. We believe earnings and revenue growth relative to consensus expectations are critical factors in determining stock price movements. Thus, our investment process focuses on identifying companies with robust and sustainable growth in revenue and earnings that are underappreciated by the market. To find that growth, we use bottom-up research, emphasizing companies whose management teams have a history of successfully executing their strategy and whose business model have sufficient profit potential. We forecast revenue and earnings growth along with other key financial metrics to assess investment potential. We then combine that company-specific analysis with our assessment of what the market is discounting for growth to form a buy/sell decision about a particular stock. We seek to capitalize on investment opportunities where a sizable gap exists between market consensus and our expectation for a company's growth prospects. We may invest in any sector and, at times, we may emphasize one or more particular sectors. In addition, our investment process is built on a foundation of continuous risk management and a strict sell discipline. We sell a company's securities when we see signs that can cause a company's growth prospects to deteriorate, as this often leads to lower valuation potential. We may also sell or trim a position when we need to raise money to fund the purchase of a better investment opportunity or when valuation has extended beyond our expectations.

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.

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.

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

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

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

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

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

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 3% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

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

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in a diversified portfolio of equity securities designed to replicate the holdings and weightings of the stocks comprising the S&P 500 Index.

The Fund is a gateway fund that invests substantially all of its assets in the Index Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies. We invest in substantially all of the common stocks comprising the S&P 500 Index and attempt to achieve at least a 95% correlation between the performance of the S&P 500 Index and the Fund's investment results, before fees and expenses. This correlation is sought regardless of market conditions. If we are unable to achieve this correlation, then we will closely monitor the performance and composition of the S&P 500 Index and adjust the Fund's securities holdings as necessary to seek the correlation.

A precise duplication of the performance of the S&P 500 Index would mean that the net asset value ("NAV") of Fund shares, including dividends and capital gains, would increase or decrease in exact proportion to changes in the S&P 500 Index. Such a 100% correlation is not feasible. Our ability to track the performance of the S&P 500 Index may be affected by, among other things, transaction costs and shareholder purchases and redemptions. We continuously monitor the performance and composition of the S&P 500 Index and adjust the Fund's portfolio as necessary to reflect any changes to the S&P 500 Index and to maintain a 95% or better performance correlation before fees and expenses. Furthermore, we may use futures to manage risk or to enhance return.

Risk [Heading]

rr_RiskHeading

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

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

Index Tracking Risk. A Fund may not achieve exact correlation between the performance of the Fund and the index it tracks due to factors such as transaction costs, shareholder purchases and redemptions and the timing of changes in the composition of the index. The Fund may invest in only a representative sample of the securities that comprise the index and may hold securities not included in the index, subjecting the Fund to increased tracking risk. Maintaining investments in securities regardless of market conditions or the investment merits of the securities in seeking to replicate an index's composition or performance could cause the Fund's returns to be lower than if the Fund employed an active strategy.

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.

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 37% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

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

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018, and is expected to change frequently.

We may also invest in equity securities of foreign issuers through American Depository Receipts (ADRs) and similar investments.

In selecting securities for the Fund, we conduct rigorous research to identify companies where the prospects for rapid earnings growth (Discovery phase) or significant change (Rediscovery phase) have yet to be well understood, and are therefore not reflected in the current stock price. This research includes meeting with the management of several hundred companies each year and conducting independent external research. Companies that fit into the Discovery phase are those with rapid long-term (3-5 year) earnings growth prospects. Companies that fit into the Rediscovery phase are those that have the prospect for sharply accelerating near-term earnings (next 12-18 months), or companies selling at a meaningful discount to their underlying asset value. We may decrease certain stock holdings when their positions rise relative to the overall portfolio. We may sell a stock in its entirety when it reaches our sell target price, which is set at the time of purchase. We may also sell stocks that experience adverse fundamental news, have significant short-term price declines, or in order to provide funds for new stock purchases.

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.

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.

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

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

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

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

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets in equity securities of small-capitalization companies.

The Fund is a gateway fund that invests substantially all of its assets in the Small Company Value Portfolio, a master portfolio with a substantially identical investment objective and substantially similar investment strategies.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2000® Index at the time of purchase. The market capitalization range of the Russell 2000® Index was approximately $33 million to $8.1 billion, as of August 31, 2018 and is expected to change frequently.

Our team's strategy is designed to provide exposure to small public companies with current stock prices that we believe do not accurately reflect their intrinsic values. We use bottom-up fundamental analysis (i.e., focusing on company-specific factors rather than broader market factors) to execute our investment philosophy which focuses on identifying three core alpha (i.e., excess returns relative to an index) drivers: value, quality partner, and contrarian. First and foremost, we believe a prospective company should possess attractive value characteristics such as being priced at a discount relative to peers and the company's own historic valuation metrics. We also seek companies that are shareholder-friendly quality partner firms demonstrating favorable cash flow generating capabilities and that have the management, business model, products and resources to drive organic growth. Lastly, the investment should exhibit what we believe are contrarian characteristics and be in a unique position for value creation, yet, overlooked by the investment community. We may sell a stock when it becomes fairly valued or when signs of fundamental deterioration surface.

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.

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