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.

Strategy [Heading] rr_StrategyHeading

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 medium-capitalization companies.

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalization within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion, as of December 31, 2015, and is expected to change frequently.

We manage a relatively focused portfolio of 30 to 50 companies that we believe enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

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

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

Principal Investment Strategies

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

  • at least 80% of the Fund's net assets in common stocks; and

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in common stocks of small-and medium-capitalization domestic and foreign companies, which we define as those with market capitalizations falling within the ranges of the Russell 2000® Index and the Russell Midcap® Index at the time of purchase. The ranges of the Russell 2000® Index and the Russell Midcap® Index were approximately $14.8 million to $5.9 billion and $14.8 million to $30.2 billion, respectively, as of December 31, 2015, and are expected to change frequently.

We invest principally in common stocks of small-and medium-capitalization 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 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- and medium-capitalization companies; and

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

We invest in equity securities of small- and medium-capitalization companies that we believe offer favorable opportunities for growth. We define small- and medium capitalization companies as those with market capitalizations at the time of purchase equal to or lower than the company with the largest market capitalization in the Russell Midcap® Index, which was approximately $30.2 billion as of December 31, 2015, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments.

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.

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 101% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading

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 medium-capitalization companies; and

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

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalization within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion as of December 31, 2015, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments.

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.

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

Principal Investment Strategies

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We may invest in the equity securities of companies of any market capitalization.

We invest in equity securities of 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 types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive situation and 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 a company's management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of a company. We then compare the private market valuation as determined by these factors to the company's public market valuation, and invest in the equity securities of those companies where we believe there is a significant gap between the two.

We may sell an investment when its market valuation 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

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 58% 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 medium-capitalization companies.

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalizations within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion as of December 31, 2015, 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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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 market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion, as of December 31, 2015, and is expected to change frequently.

We manage a relatively focused portfolio of 30 to 50 companies that we believe enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

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

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

Principal Investment Strategies

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

  • at least 80% of the Fund's net assets in common stocks; and

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in common stocks of small-and medium-capitalization domestic and foreign companies, which we define as those with market capitalizations falling within the ranges of the Russell 2000® Index and the Russell Midcap® Index at the time of purchase. The ranges of the Russell 2000® Index and the Russell Midcap® Index were approximately $14.8 million to $5.9 billion and $14.8 million to $30.2 billion, respectively, as of December 31, 2015, and are expected to change frequently.

We invest principally in common stocks of small-and medium-capitalization 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.

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

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

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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

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 87% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading

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- and medium-capitalization companies; and

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

We invest in equity securities of small- and medium-capitalization companies that we believe offer favorable opportunities for growth. We define small- and medium capitalization companies as those with market capitalizations at the time of purchase equal to or lower than the company with the largest market capitalization in the Russell Midcap® Index, which was approximately $30.2 billion as of December 31, 2015, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments.

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.

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 42% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We may invest in the equity securities of companies of any market capitalization.

We invest in equity securities of 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 types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive situation and 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 a company's management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of a company. We then compare the private market valuation as determined by these factors to the company's public market valuation, and invest in the equity securities of those companies where we believe there is a significant gap between the two.

We may sell an investment when its market valuation 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 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 medium-capitalization companies.

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalizations within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion as of December 31, 2015, 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.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalization within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion, as of December 31, 2015, and is expected to change frequently.

We manage a relatively focused portfolio of 30 to 50 companies that we believe enables us to provide adequate diversification while allowing the composition and performance of the portfolio to behave differently than the market.

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

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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 51% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

  • at least 80% of the Fund's net assets in common stocks; and

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in common stocks of small-and medium-capitalization domestic and foreign companies, which we define as those with market capitalizations falling within the ranges of the Russell 2000® Index and the Russell Midcap® Index at the time of purchase. The ranges of the Russell 2000® Index and the Russell Midcap® Index were approximately $14.8 million to $5.9 billion and $14.8 million to $30.2 billion, respectively, as of December 31, 2015, and are expected to change frequently.

We invest principally in common stocks of small-and medium-capitalization 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.

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

Under normal circumstances, we invest:

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

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

We invest in equity securities of small- and medium-capitalization companies that we believe offer favorable opportunities for growth. We define small- and medium capitalization companies as those with market capitalizations at the time of purchase equal to or lower than the company with the largest market capitalization in the Russell Midcap® Index, which was approximately $30.2 billion as of December 31, 2015, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments.

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.

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

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 101% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading

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 medium-capitalization companies; and

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

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalization within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion as of December 31, 2015, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments.

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.

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 42% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, we invest:

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

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We may invest in the equity securities of companies of any market capitalization.

We invest in equity securities of 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 types of analysis. We carry out a fundamental analysis of a company's cash flows, asset valuations, competitive situation and 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 a company's management, even meeting with management in certain situations. Finally, we focus on the long-term strategic direction of a company. We then compare the private market valuation as determined by these factors to the company's public market valuation, and invest in the equity securities of those companies where we believe there is a significant gap between the two.

We may sell an investment when its market valuation 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.

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

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 medium-capitalization companies.

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalizations within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion as of December 31, 2015, 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 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 51% 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 common stocks; and

  • up to 25% of the Fund's total assets in equity securities of foreign issuers, including ADRs and similar investments.

We invest principally in common stocks of small-and medium-capitalization domestic and foreign companies, which we define as those with market capitalizations falling within the ranges of the Russell 2000® Index and the Russell Midcap® Index at the time of purchase. The ranges of the Russell 2000® Index and the Russell Midcap® Index were approximately $14.8 million to $5.9 billion and $14.8 million to $30.2 billion, respectively, as of December 31, 2015, and are expected to change frequently.

We invest principally in common stocks of small-and medium-capitalization 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.

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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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- and medium-capitalization companies; and

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

We invest in equity securities of small- and medium-capitalization companies that we believe offer favorable opportunities for growth. We define small- and medium capitalization companies as those with market capitalizations at the time of purchase equal to or lower than the company with the largest market capitalization in the Russell Midcap® Index, which was approximately $30.2 billion as of December 31, 2015, and is expected to change frequently. We may also invest in equity securities of foreign issuers through ADRs and similar investments.

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

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 58% 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 medium-capitalization companies.

We invest principally in equity securities of medium-capitalization companies, which we define as securities of companies with market capitalizations within the range of the Russell Midcap® Index at the time of purchase. The market capitalization range of the Russell Midcap® Index was approximately $14.8 million to $30.2 billion as of December 31, 2015, 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.

Investment Style Risk. Securities of a particular investment style, such as a growth style or value style, 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.

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