(WFA U.S. Equity Funds - Institutional Class) | (Wells Fargo Disciplined Small Cap Fund)

Investment Objective

The Fund seeks long-term capital appreciation.

Fees and Expenses

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - (Wells Fargo Disciplined Small Cap Fund)	Institutional Class ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of offering price)	none

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

^[1]

Annual Fund Operating Expenses - (Wells Fargo Disciplined Small Cap Fund)	Institutional Class ­
Management Fees	0.50%
Distribution (12b-1) Fees	none
Other Expenses	0.21%
Acquired Fund Fees and Expenses	0.06%
Total Annual Fund Operating Expenses	0.77%
Fee Waivers	(0.11%)
Total Annual Fund Operating Expenses After Fee Waivers	0.66%	[1]

Example of Expenses

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

Expense Example - (Wells Fargo Disciplined Small Cap Fund)	1 Year	3 Years	5 Years	10 Years
Institutional Class | ­ | USD ($)	67	235	417	944

Portfolio Turnover

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

Principal Investment Strategies

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Principal Investment Risks

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

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.

Performance

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.

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 27% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.

We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently.

We invest in companies that we believe are underpriced yet have attractive growth prospects. Our analysis is based on the determination of a company's "private market valuation," which is the price an investor would be willing to pay for the entire company. We determine a company's private market valuation based upon several different types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive factors, and other industry specific factors. We also gauge the company's management strength, financial health, and growth potential in determining a company's private market valuation. We place an emphasis on company management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of the company. We then compare the private market valuation, as determined by these factors to the company's public market valuation, and invest in the securities of those companies where we believe there is a significant gap between the two. We may sell an investment when its price no longer compares favorably with the company's private market valuation. In addition, we may choose to sell an investment where the fundamentals deteriorate or the strategy of the management or the management itself changes.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 53% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

Principal Investment Risks

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

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.

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.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 36% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

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

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

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

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 Fund seeks long-term capital appreciation.

Fees and Expenses

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

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees - (Wells Fargo Special Small Cap Value Fund)	Institutional Class ­
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	none
Maximum deferred sales charge (load) (as a percentage of offering price)	none

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

Annual Fund Operating Expenses - (Wells Fargo Special Small Cap Value Fund)	Institutional Class ­
Management Fees	0.82%
Distribution (12b-1) Fees	none
Other Expenses	0.16%
Total Annual Fund Operating Expenses	0.98%
Fee Waivers	(0.04%)
Total Annual Fund Operating Expenses After Fee Waivers	0.94%	[1]

Example of Expenses

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

Expense Example - (Wells Fargo Special Small Cap Value Fund)	1 Year	3 Years	5 Years	10 Years
Institutional Class | ­ | USD ($)	96	308	538	1,198

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Principal Investment Risks

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

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

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 44% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 15% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently.

We seek to identify companies that have the prospect for improving sales and earnings growth rates, enjoy a competitive advantage (for example, dominant market share) and that we believe have effective management with a history of making investments that are in the best interests of shareholders (for example, companies with a history of earnings and sales growth that are in excess of total asset growth). We pay particular attention to balance sheet metrics such as changes in working capital, property, plant and equipment growth, inventory levels, accounts receivable, and acquisitions. We also look at how management teams allocate capital in order to drive future cash flow. Price objectives are determined based on industry specific valuation methodologies including relative price-to-earnings multiples, price- to-book value, operating profit margin trends, enterprise value to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) and free cash flow yield. In addition to meeting with management, we take a surround the company approach by surveying a company's vendors, distributors, competitors and customers to obtain multiple perspectives that help us make better investment decisions. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable risk/reward relationship to fair valuation, which we define as the value of the company (i.e. our price target for the stock) relative to where the stock is currently trading. We may invest in any sector, and at times we may emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth prospects, reaches our target price, or to take advantage of a better investment opportunity.

Portfolio Turnover

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

Principal Investment Strategies

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Principal Investment Risks

During the most recent fiscal year, the Fund's portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.

We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently.

We invest in companies that we believe are underpriced yet have attractive growth prospects. Our analysis is based on the determination of a company's "private market valuation," which is the price an investor would be willing to pay for the entire company. We determine a company's private market valuation based upon several different types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive factors, and other industry specific factors. We also gauge the company's management strength, financial health, and growth potential in determining a company's private market valuation. We place an emphasis on company management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of the company. We then compare the private market valuation, as determined by these factors to the company's public market valuation, and invest in the securities of those companies where we believe there is a significant gap between the two. We may sell an investment when its price no longer compares favorably with the company's private market valuation. In addition, we may choose to sell an investment where the fundamentals deteriorate or the strategy of the management or the management itself changes.

Principal Investment Risks

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

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.

Fees and Expenses

These tables are intended to help you understand the various costs and expenses you will pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the aggregate in specified classes of certain Wells Fargo Funds. More information about these and other discounts is available from your financial professional and in "Share Class Features" and "Reductions and Waivers of Sales Charges" on pages 38 and 39 of the Prospectus and "Additional Purchase and Redemption Information" on page 59 of the Statement of Additional Information. Investors who purchase through certain intermediaries may be subject to different sales charge discounts than those outlined shares in these sections. Please see Appendix A on page 56 for further information.

Example of Expenses

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

Assuming Redemption at End of Period

Assuming No Redemption

Expense Example, No Redemption - (Wells Fargo Small Cap Core Fund)	1 Year	3 Years	5 Years	10 Years
Class C | ­ | USD ($)	213	718	1,249	2,704

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 53% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

Principal Investment Risks

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

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.

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

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 36% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

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

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

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

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.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Example of Expenses

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

Assuming Redemption at End of Period

Expense Example - (Wells Fargo Traditional Small Cap Growth Fund) - ­ - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A	695	1,007	1,340	2,281
Class C	303	688	1,199	2,603

Assuming No Redemption

Expense Example, No Redemption - (Wells Fargo Traditional Small Cap Growth Fund)	1 Year	3 Years	5 Years	10 Years
Class C | ­ | USD ($)	203	688	1,199	2,603

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 44% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 15% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently.

We seek to identify companies that have the prospect for improving sales and earnings growth rates, enjoy a competitive advantage (for example, dominant market share) and that we believe have effective management with a history of making investments that are in the best interests of shareholders (for example, companies with a history of earnings and sales growth that are in excess of total asset growth). We pay particular attention to balance sheet metrics such as changes in working capital, property, plant and equipment growth, inventory levels, accounts receivable, and acquisitions. We also look at how management teams allocate capital in order to drive future cash flow. Price objectives are determined based on industry specific valuation methodologies including relative price-to-earnings multiples, price- to-book value, operating profit margin trends, enterprise value to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) and free cash flow yield. In addition to meeting with management, we take a surround the company approach by surveying a company's vendors, distributors, competitors and customers to obtain multiple perspectives that help us make better investment decisions. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable risk/reward relationship to fair valuation, which we define as the value of the company (i.e. our price target for the stock) relative to where the stock is currently trading. We may invest in any sector, and at times we may emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth prospects, reaches our target price, or to take advantage of a better investment opportunity.

Principal Investment Risks

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

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

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 41% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

The market capitalization range of the Russell 2000® Index was approximately $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.

We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently.

We invest in companies that we believe are underpriced yet have attractive growth prospects. Our analysis is based on the determination of a company's "private market valuation," which is the price an investor would be willing to pay for the entire company. We determine a company's private market valuation based upon several different types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive factors, and other industry specific factors. We also gauge the company's management strength, financial health, and growth potential in determining a company's private market valuation. We place an emphasis on company management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of the company. We then compare the private market valuation, as determined by these factors to the company's public market valuation, and invest in the securities of those companies where we believe there is a significant gap between the two. We may sell an investment when its price no longer compares favorably with the company's private market valuation. In addition, we may choose to sell an investment where the fundamentals deteriorate or the strategy of the management or the management itself changes.

Principal Investment Risks

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

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.

Example of Expenses

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

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

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 53% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

Principal Investment Risks

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

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.

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

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 36% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

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

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

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

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.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 44% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 15% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently.

We seek to identify companies that have the prospect for improving sales and earnings growth rates, enjoy a competitive advantage (for example, dominant market share) and that we believe have effective management with a history of making investments that are in the best interests of shareholders (for example, companies with a history of earnings and sales growth that are in excess of total asset growth). We pay particular attention to balance sheet metrics such as changes in working capital, property, plant and equipment growth, inventory levels, accounts receivable, and acquisitions. We also look at how management teams allocate capital in order to drive future cash flow. Price objectives are determined based on industry specific valuation methodologies including relative price-to-earnings multiples, price- to-book value, operating profit margin trends, enterprise value to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) and free cash flow yield. In addition to meeting with management, we take a surround the company approach by surveying a company's vendors, distributors, competitors and customers to obtain multiple perspectives that help us make better investment decisions. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable risk/reward relationship to fair valuation, which we define as the value of the company (i.e. our price target for the stock) relative to where the stock is currently trading. We may invest in any sector, and at times we may emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth prospects, reaches our target price, or to take advantage of a better investment opportunity.

Class R6 | ­ | USD ($)	57	203	362	824

Portfolio Turnover

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

Principal Investment Strategies

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Principal Investment Risks

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

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

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 53% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

Principal Investment Risks

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

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.

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.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 36% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

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

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

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

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.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Principal Investment Risks

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

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

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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

Principal Investment Strategies

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.

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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.

We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently.

We invest in companies that we believe are underpriced yet have attractive growth prospects. Our analysis is based on the determination of a company's "private market valuation," which is the price an investor would be willing to pay for the entire company. We determine a company's private market valuation based upon several different types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive factors, and other industry specific factors. We also gauge the company's management strength, financial health, and growth potential in determining a company's private market valuation. We place an emphasis on company management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of the company. We then compare the private market valuation, as determined by these factors to the company's public market valuation, and invest in the securities of those companies where we believe there is a significant gap between the two. We may sell an investment when its price no longer compares favorably with the company's private market valuation. In addition, we may choose to sell an investment where the fundamentals deteriorate or the strategy of the management or the management itself changes.

Under normal circumstances, we invest:

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

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

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.

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.

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

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 36% of the average value of its portfolio.

Principal Investment Strategies

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; and

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

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.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify 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.

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 44% of the average value of its portfolio.

Principal Investment Strategies

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; and

• up to 15% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently.

We seek to identify companies that have the prospect for improving sales and earnings growth rates, enjoy a competitive advantage (for example, dominant market share) and that we believe have effective management with a history of making investments that are in the best interests of shareholders (for example, companies with a history of earnings and sales growth that are in excess of total asset growth). We pay particular attention to balance sheet metrics such as changes in working capital, property, plant and equipment growth, inventory levels, accounts receivable, and acquisitions. We also look at how management teams allocate capital in order to drive future cash flow. Price objectives are determined based on industry specific valuation methodologies including relative price-to-earnings multiples, price- to-book value, operating profit margin trends, enterprise value to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) and free cash flow yield. In addition to meeting with management, we take a surround the company approach by surveying a company's vendors, distributors, competitors and customers to obtain multiple perspectives that help us make better investment decisions. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable risk/reward relationship to fair valuation, which we define as the value of the company (i.e. our price target for the stock) relative to where the stock is currently trading. We may invest in any sector, and at times we may emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth prospects, reaches our target price, or to take advantage of a better investment opportunity.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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 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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

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 27% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.

We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently.

We invest in companies that we believe are underpriced yet have attractive growth prospects. Our analysis is based on the determination of a company's "private market valuation," which is the price an investor would be willing to pay for the entire company. We determine a company's private market valuation based upon several different types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive factors, and other industry specific factors. We also gauge the company's management strength, financial health, and growth potential in determining a company's private market valuation. We place an emphasis on company management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of the company. We then compare the private market valuation, as determined by these factors to the company's public market valuation, and invest in the securities of those companies where we believe there is a significant gap between the two. We may sell an investment when its price no longer compares favorably with the company's private market valuation. In addition, we may choose to sell an investment where the fundamentals deteriorate or the strategy of the management or the management itself changes.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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 small-capitalization companies; and

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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.

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

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 36% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

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; and

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

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.

To the extent that the Manager is waiving fees or reimbursing expenses, the example assumes that such waiver or reimbursement will only be in place through the date noted above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 41% 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.

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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; and

• up to 15% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently.

We seek to identify companies that have the prospect for improving sales and earnings growth rates, enjoy a competitive advantage (for example, dominant market share) and that we believe have effective management with a history of making investments that are in the best interests of shareholders (for example, companies with a history of earnings and sales growth that are in excess of total asset growth). We pay particular attention to balance sheet metrics such as changes in working capital, property, plant and equipment growth, inventory levels, accounts receivable, and acquisitions. We also look at how management teams allocate capital in order to drive future cash flow. Price objectives are determined based on industry specific valuation methodologies including relative price-to-earnings multiples, price- to-book value, operating profit margin trends, enterprise value to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) and free cash flow yield. In addition to meeting with management, we take a surround the company approach by surveying a company's vendors, distributors, competitors and customers to obtain multiple perspectives that help us make better investment decisions. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable risk/reward relationship to fair valuation, which we define as the value of the company (i.e. our price target for the stock) relative to where the stock is currently trading. We may invest in any sector, and at times we may emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth prospects, reaches our target price, or to take advantage of a better 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.

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]

rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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 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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Under normal circumstances, we invest:

• at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes, if any) in equity securities of small-capitalization companies.

We invest principally in equity securities of small-capitalization companies, which we define as companies within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently.

We invest in companies that we believe are underpriced yet have attractive growth prospects. Our analysis is based on the determination of a company's "private market valuation," which is the price an investor would be willing to pay for the entire company. We determine a company's private market valuation based upon several different types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive factors, and other industry specific factors. We also gauge the company's management strength, financial health, and growth potential in determining a company's private market valuation. We place an emphasis on company management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of the company. We then compare the private market valuation, as determined by these factors to the company's public market valuation, and invest in the securities of those companies where we believe there is a significant gap between the two. We may sell an investment when its price no longer compares favorably with the company's private market valuation. In addition, we may choose to sell an investment where the fundamentals deteriorate or the strategy of the management or the management itself changes.

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]

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 53% of the average value of its portfolio.

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; and

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

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.

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.

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.

Under normal circumstances, we invest:

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

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

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

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

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.

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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 small-capitalization companies; and

• up to 15% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently.

We seek to identify companies that have the prospect for improving sales and earnings growth rates, enjoy a competitive advantage (for example, dominant market share) and that we believe have effective management with a history of making investments that are in the best interests of shareholders (for example, companies with a history of earnings and sales growth that are in excess of total asset growth). We pay particular attention to balance sheet metrics such as changes in working capital, property, plant and equipment growth, inventory levels, accounts receivable, and acquisitions. We also look at how management teams allocate capital in order to drive future cash flow. Price objectives are determined based on industry specific valuation methodologies including relative price-to-earnings multiples, price- to-book value, operating profit margin trends, enterprise value to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) and free cash flow yield. In addition to meeting with management, we take a surround the company approach by surveying a company's vendors, distributors, competitors and customers to obtain multiple perspectives that help us make better investment decisions. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable risk/reward relationship to fair valuation, which we define as the value of the company (i.e. our price target for the stock) relative to where the stock is currently trading. We may invest in any sector, and at times we may emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth prospects, reaches our target price, or to take advantage of a better investment opportunity.

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.

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 $13.8 million to $12.64 billion, as of May 31, 2018 and is expected to change frequently.

We employ a risk controlled investment approach in seeking to construct a broadly diversified portfolio of companies with characteristics similar to the Russell 2000® Index and a superior valuation and earnings profile. Our research, which utilizes a combination of quantitative methods and fundamental analysis, identifies companies based on valuation, earnings and trading momentum characteristics that give a comprehensive view of each company's relative valuation, operational and financial performance, and stock price behavior. Our approach seeks to achieve positive excess returns relative to the Russell 2000® Index (which may include both value and growth stocks) by using stock selection to take controlled active risks in a portfolio that is similar to the benchmark. We regularly review the investments of the portfolio and may sell a portfolio holding when, among other reasons, we believe there is deterioration in the underlying fundamentals of the business, or we have identified a more attractive investment opportunity.

We may actively trade portfolio securities, which may lead to higher transaction costs that may affect the Fund's performance. In addition, active trading of portfolio securities may lead to higher taxes if your shares are held in a taxable account.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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; and

• up to 10% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

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 $13.8 million to $12.64 billion, as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers, including ADRs and similar investments. Generally, we avoid investments in issuers we deem to have significant alcohol, gaming or tobacco business.

We utilize a combination of quantitative methods and fundamental analysis to select a core portfolio of small capitalization companies that we believe are relatively undervalued and exhibit the likelihood to meet or exceed future earnings expectations. Our quantitative analysis is based on a proprietary total composite model that considers valuation, earnings and trading momentum characteristics to rank securities. Stocks that are attractively ranked by the total composite model are candidates for purchase. Such candidates undergo further qualitative analysis, which may include an evaluation of a company's management strength, products and/or services, competition and risk profile. This disciplined process leads to a focused, target portfolio of approximately 60 securities that are diversified among major economic sectors. In general, a stock may be sold if it has declining earnings expectations or a significantly overvalued stock price, as indicated by lower rankings within the total composite model. Upon the sale of any security, we seek to invest the proceeds in the most attractive security, in light of all relevant considerations, in which the Fund may invest in accordance with the Fund's investment restrictions.

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.

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.

Under normal circumstances, we invest:

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

• up to 30% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in equity securities of small-capitalization companies, which we define as companies with market capitalizations within the range of the Russell 2500TM Index at the time of purchase. The market capitalization range of the Russell 2500TM Index was $13.8 million to $24.05 billion as of May 31, 2018, and is expected to change frequently. We may also invest in equity securities of foreign issuers including ADRs and similar investments. As a hedging strategy, the Fund may write put and call options, meaning that the Fund sells an option to another party giving that party the right to either sell a stock to (put) or buy a stock from (call) the Fund at a predetermined price in the future. Whether or not this hedging strategy is successful depends on a variety of factors, particularly our ability to predict movements of the price of the hedged stock. Furthermore, we may use options to enhance return.

We employ a multi-faceted investment process that consists of quantitative idea generation and rigorous fundamental research. This process involves identifying companies that we believe exhibit attractive valuation characteristics and warrant further research. We then conduct fundamental research to find securities in small-capitalization companies with a positive dynamic for change that could move the price of such securities higher. The positive dynamic may include a change in management team, a new product or service, corporate restructuring, an improved business plan, a change in the regulatory environment, or the right time for the industry in its market cycle. We typically sell a security when its fundamentals deteriorate, its relative valuation versus the peer group and market becomes expensive, or for risk management considerations. We believe the combination of buying the securities of undervalued small-capitalization companies with positive dynamics for change limits our downside risk while allowing us to potentially participate in significant upside appreciation in the price of such securities.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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

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

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.

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 41% of the average value of its portfolio.

Principal Investment Strategies

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.

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 $13.8 million to $12.64 billion as of May 31, 2018, and is expected to change frequently.

We look for undervalued companies that we believe have the potential for above average capital appreciation with below average risk. Rigorous fundamental research drives our search for companies with favorable reward-to-risk ratios and that possess, a long-term competitive advantage provided by a durable asset base, strong balance sheets, and sustainable and superior cash flows. Typical investments include stocks of companies that are generally out of favor in the marketplace, or are undergoing reorganization or other corporate action that may create above-average price appreciation. We regularly review the investments of the portfolio and may sell a portfolio holding when a stock nears its price target, downside risks increase considerably, the company's fundamentals have deteriorated, or we identify a more attractive investment opportunity.
