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. Since the Fund has not yet completed a full fiscal year, the portfolio turnover rate is not available.

Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
The Fund is a diversified investment that invests substantially all of its investable assets in the GMO Benchmark-Free Allocation Fund (the "Benchmark-Free Allocation Fund"), an investment company managed by Grantham, Mayo, Van Otterloo & Co. LLC ("GMO"). GMO seeks to achieve Benchmark-Free Allocation Fund's investment objective by investing in asset classes that GMO believes offer the most attractive return and risk opportunities. The asset classes include:
-
U.S. and foreign equity, including emerging markets;
-
U.S. and foreign fixed income, including emerging markets; and
-
alternative asset classes, including real estate and commodities.
GMO uses multi-year forecasts of returns and risk for asset classes to determine Benchmark-Free Allocation Fund's allocations. The factors considered and investment methods used by GMO can change over time.
Benchmark-Free Allocation Fund is structured as a fund of funds and gains its investment exposures primarily by investing in the GMO Implementation Fund. In addition, Benchmark-Free Allocation Fund may invest in other GMO Funds (together with GMO Implementation Fund, the "underlying funds"), principally GMO Alpha Only Fund, GMO Debt Opportunities Fund, GMO Alternative Asset Opportunity Fund, GMO Emerging Country Debt Fund, and GMO Flexible Equities Fund. GMO Implementation Fund is permitted to invest in any asset class. Benchmark-Free Allocation Fund also may invest in securities or derivatives directly.
Benchmark-Free Allocation Fund seeks annualized excess returns of 5% (net of Benchmark-Free Allocation Fund fees) above the Consumer Price Index, with annualized volatility of 5-10%, over a complete market cycle. GMO does not manage Benchmark-Free Allocation Fund to, or control Benchmark-Free Allocation Fund's risk relative to, any securities index or securities benchmark.
Benchmark-Free Allocation Fund is permitted to invest (through GMO Implementation Fund, another underlying fund or directly) in any asset class, country, or sector and at times may have substantial exposure to a single asset class, country, or sector. In addition, Benchmark-Free Allocation Fund is not restricted in its exposure to any particular market and may invest in securities of companies of any market capitalization. Benchmark-Free Allocation Fund may have indirect exposure to derivatives and short sales through its investment in GMO Implementation Fund and other underlying funds. GMO's ability to shift investments within GMO Implementation Fund and between it and other underlying funds is not subject to any limits.
Benchmark-Free Allocation Fund also may invest in GMO U.S. Treasury Fund and unaffiliated money market funds.
While the Fund invests substantially all of its investable assets in the Benchmark-Free Allocation Fund, the Fund may hold cash for short periods of time in order to mitigate the expenses associated with the purchase and sale of shares of the Benchmark-Free Allocation Fund.

Principal Investment Risks
|
|
Risk Narrative [Text Block] |
rr_RiskNarrativeTextBlock |
Because the Fund invests substantially all of its investable assets in Benchmark-Free Allocation Fund, which, in turn, invests all of its assets in a number of underlying funds, the following principal risks are those risks that result from the Fund's indirect investments in the underlying funds or direct investment in Benchmark-Free Allocation Fund. In this section, references to the Fund should be read to include the Fund, Benchmark-Free Allocation Fund and the underlying funds, as appropriate.
The Fund's performance will not correlate perfectly with that of Benchmark-Free Allocation Fund due to the impact of the Fund's fees and expenses and to the timing and magnitude of cash flows into and out of the Fund which will create cash balances that cause the Fund's performance to deviate from the performance of the Benchmark-Free Allocation Fund.
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.
Commodities Risk. Commodities prices can be extremely volatile and exposure to commodities can cause the net asset value of the Fund's shares to decline and fluctuate in a rapid and unpredictable manner.
Counterparty Risk. The Fund runs the risk that the counterparty to a derivatives contract, a clearing member used by the Fund to hold a cleared derivatives contract, or a borrower of the Fund's securities will be unable or unwilling to make timely settlement payments, return the Fund's margin or otherwise honor its obligations.
Credit Risk. The Fund runs the risk that the issuer or guarantor of a fixed income investment or the obligor of an obligation underlying an asset-backed security will be unable or unwilling to satisfy its obligations to pay principal and interest or otherwise to honor its obligations in a timely manner. The market price of a fixed income investment will normally decline as a result of the issuer's, guarantor's, or obligor's failure to meet its payment obligations. Below investment grade securities (also known as "junk bonds") have speculative characteristics, and changes in economic conditions or other circumstances are more likely to impair the capacity of issuers to make principal and interest payments than is the case with issuers of investment grade securities.
Currency Risk. Fluctuations in exchange rates can adversely affect the market value of foreign currency holdings and investments denominated in foreign currencies. In addition, hedging a foreign currency can have a negative effect on performance if the U.S. dollar declines in value relative to that currency.
Derivatives Risk. The use of derivatives involves the risk that their value may not move as expected relative to the value of the underlying assets, rates or indices. Derivatives also present other risks, including market risk, liquidity risk, currency risk and counterparty risk.
Focused Investment Risk. Focusing investments in countries, regions, sectors or companies or in industries with high positive correlations to one another creates more risk than if the Fund's investments were less correlated.
Foreign Investment Risk. The market prices of many foreign securities fluctuate more than those of U.S. securities. Many foreign markets are less stable, smaller, less liquid and less regulated than U.S. markets, and the cost of trading in those markets often is higher than in U.S. markets. Foreign portfolio transactions generally involve higher commission rates, transfer taxes and custodial costs than similar transactions in the U.S. In addition, the Fund may be subject to foreign taxes on capital gains or other income payable on foreign investments, on transactions in those investments and on the repatriation of proceeds generated from those investments. Also, many foreign markets require a license for the fund to invest directly in those markets, and the fund is subject to the risk that it could not invest if its license were terminated or suspended. In some foreign markets, prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks with respect to participating brokers, custodians, clearing banks or other clearing agents, escrow agents and issuers. Further, adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. These and other risks (e.g., nationalization, expropriation or other confiscation of assets of foreign issuers) tend to be greater for investments in companies tied economically to emerging countries, the economies ofwhich tend to be more volatile than the economies of developed countries.
Fund of Funds Risk. The Fund is indirectly exposed to all of the risks of an investment in the underlying funds in which it invests, including the risk that those underlying funds will not perform as expected. Because the Fund bears the fees and expenses of the underlying funds in which it invests, a reallocation of the Fund's investments to underlying funds with higher fees or expenses will increase the Fund's total expenses. The fees and expenses associated with an investment in the Fund are less predictable than those associated with an investment in funds that charge a fixed management fee.
Large Shareholder Risk. To the extent a large number of shares of the Fund is held by a single shareholder (e.g., institutional investors), the Fund is subject to the risk that a redemption by that shareholder of all or a large portion of its shares will disrupt the Fund's operations.
Leveraging Risk. The use of reverse repurchase agreements and other derivatives and securities lending creates leverage. Leverage increases the Fund's losses when the value of its investments (including derivatives) declines.
Liquidity Risk. Low trading volume, lack of a market maker, large position size, or legal restrictions may limit or prevent the Fund or an underlying fund from selling particular securities or unwinding derivative positions at desirable prices.
Management and Operational Risk. Benchmark-Free Allocation Fund and the underlying funds run the risk that GMO's investment techniques will fail to produce desired results (including the annualized excess returns Benchmark-Free Allocation seeks above the Consumer Price Index). Benchmark-Free Allocation Fund's and the underlying funds' portfolio managers may use quantitative analyses and models, and any imperfections, errors, or limitations in those analyses and models could affect the ability of the portfolio managers to implement such fund's strategies. By necessity, these analyses and models make simplifying assumptions that limit their efficacy. Models that appear to explain prior market data can fail to predict future market events. Further, the data used in models may be inaccurate and may not include the most recent information about a company or a security. The Fund also runs the risk that GMO's assessment of an investment may be wrong or that deficiencies in GMO's or another service provider's internal systems or controls will cause losses or impair operations for Benchmark-Free Allocation Fund or the underlying funds.
Market Disruption and Geopolitical Risk. Geopolitical and other events may disrupt securities markets and adversely affect global economies and markets. Those events as well as other changes in foreign and domestic economic and political conditions, could adversely affect the value of the Fund's investments.
Market Risk - Asset-Backed Securities. The market price of fixed income investments with complex structures, such as asset backed securities, can decline due to a number of factors, including market uncertainty about their credit quality and the reliability of their payment streams. Payment streams associated with asset-backed securities held by the Fund depend on many factors (e.g., the cash flow generated by the assets backing the securities, the deal structure, the credit worthiness of any credit-support provider, and the reliability of various other service providers with access to the payment stream), and a problem in any one of these areas can lead to a reduction in the payment stream GMO expected the Fund to receive at the time the Fund purchased the asset-backed security.
Market Risk - Equities. The market prices of equities may decline due to factors affecting the issuing companies, their industries, or the economy and equity markets generally. If an underlying fund purchases equities at a discount from their value as determined by GMO, the Benchmark-Free Allocation Fund runs the risk that the market prices of these investments will not appreciate or will decline for a variety of reasons, one of which may be GMO's overestimation of the value of those investments. An underlying fund also may purchase equities that typically trade at higher multiples of current earnings than other securities, and the market prices of these investments often are more sensitive to changes in future earnings expectations than the market prices of equities trading at lower multiples. In addition, the value of the Fund's shares will be adversely affected if the equities that are subject of the underlying fund's short position appreciate in value.
Market Risk - Fixed Income Investments. The market price of a fixed income investment can decline due to a number of market-related factors, including rising interest rates and widening credit spreads, or decreased liquidity stemming from the market's uncertainty about the value of a fixed income investment (or class of fixed income investments).
Natural Resources Risk. To the extent an underlying fund concentrates its assets in the natural resources sector, the value of its portfolio is subject to factors affecting the natural resources industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries.
Non-Diversified Funds Risk. The Fund invests a portion of its assets in shares of one or more other funds that are not "diversified" investment companies within the meaning of the Investment Company Act of 1940 (the "1940 Act"). This means they are allowed to invest in the securities of a relatively small number of issuers and/or non-U.S. currencies. As a result, they may be subject to greater credit, market and other risks, and poor performance by a single issuer may have a greater impact on their performance, than if they were "diversified." The Fund may invest without limitation in funds that are not diversified.
Options Risk. The market price of options written by an underlying fund will be affected by many factors, including changes in the market price or dividend rates of underlying securities (or in the case of indices, the securities comprising such indices); changes in interest rates or exchange rates; changes in the actual or perceived volatility of the relevant stock market and underlying securities; and the time remaining before an option's expiration.
Short Sales Risk. The Fund runs the risk that an underlying fund's loss on a short sales of securities that the underlying Fund does not own is unlimited.
Smaller Company Risk. Smaller companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, or may lack managers with experience or depend on a few key employees. The securities of small- and mid-cap companies often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalization.
Real Estate Risk. To the extent an underlying fund concentrates its assets in real estate-related investments, the value of its portfolio is subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries.

Risk Nondiversified Status [Text] |
rr_RiskNondiversifiedStatus |
Non-Diversified Funds Risk. The Fund invests a portion of its assets in shares of one or more other funds that are not "diversified" investment companies within the meaning of the Investment Company Act of 1940 (the "1940 Act"). This means they are allowed to invest in the securities of a relatively small number of issuers and/or non-U.S. currencies. As a result, they may be subject to greater credit, market and other risks, and poor performance by a single issuer may have a greater impact on their performance, than if they were "diversified." The Fund may invest without limitation in funds that are not diversified. |

Because the Fund invests substantially all of its investable assets in Benchmark-Free Allocation Fund, which, in turn, invests all of its assets in a number of underlying funds, the following principal risks are those risks that result from the Fund's indirect investments in the underlying funds or direct investment in Benchmark-Free Allocation Fund. In this section, references to the Fund should be read to include the Fund, Benchmark-Free Allocation Fund and the underlying funds, as appropriate.
The Fund's performance will not correlate perfectly with that of Benchmark-Free Allocation Fund due to the impact of the Fund's fees and expenses and to the timing and magnitude of cash flows into and out of the Fund which will create cash balances that cause the Fund's performance to deviate from the performance of the Benchmark-Free Allocation Fund.
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.
Commodities Risk. Commodities prices can be extremely volatile and exposure to commodities can cause the net asset value of the Fund's shares to decline and fluctuate in a rapid and unpredictable manner.
Counterparty Risk. The Fund runs the risk that the counterparty to a derivatives contract, a clearing member used by the Fund to hold a cleared derivatives contract, or a borrower of the Fund's securities will be unable or unwilling to make timely settlement payments, return the Fund's margin or otherwise honor its obligations.
Credit Risk. The Fund runs the risk that the issuer or guarantor of a fixed income investment or the obligor of an obligation underlying an asset-backed security will be unable or unwilling to satisfy its obligations to pay principal and interest or otherwise to honor its obligations in a timely manner. The market price of a fixed income investment will normally decline as a result of the issuer's, guarantor's, or obligor's failure to meet its payment obligations. Below investment grade securities (also known as "junk bonds") have speculative characteristics, and changes in economic conditions or other circumstances are more likely to impair the capacity of issuers to make principal and interest payments than is the case with issuers of investment grade securities.
Currency Risk. Fluctuations in exchange rates can adversely affect the market value of foreign currency holdings and investments denominated in foreign currencies. In addition, hedging a foreign currency can have a negative effect on performance if the U.S. dollar declines in value relative to that currency.
Derivatives Risk. The use of derivatives involves the risk that their value may not move as expected relative to the value of the underlying assets, rates or indices. Derivatives also present other risks, including market risk, liquidity risk, currency risk and counterparty risk.
Focused Investment Risk. Focusing investments in countries, regions, sectors or companies or in industries with high positive correlations to one another creates more risk than if the Fund's investments were less correlated.
Foreign Investment Risk. The market prices of many foreign securities fluctuate more than those of U.S. securities. Many foreign markets are less stable, smaller, less liquid and less regulated than U.S. markets, and the cost of trading in those markets often is higher than in U.S. markets. Foreign portfolio transactions generally involve higher commission rates, transfer taxes and custodial costs than similar transactions in the U.S. In addition, the Fund may be subject to foreign taxes on capital gains or other income payable on foreign investments, on transactions in those investments and on the repatriation of proceeds generated from those investments. Also, many foreign markets require a license for the fund to invest directly in those markets, and the fund is subject to the risk that it could not invest if its license were terminated or suspended. In some foreign markets, prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks with respect to participating brokers, custodians, clearing banks or other clearing agents, escrow agents and issuers. Further, adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. These and other risks (e.g., nationalization, expropriation or other confiscation of assets of foreign issuers) tend to be greater for investments in companies tied economically to emerging countries, the economies ofwhich tend to be more volatile than the economies of developed countries.
Fund of Funds Risk. The Fund is indirectly exposed to all of the risks of an investment in the underlying funds in which it invests, including the risk that those underlying funds will not perform as expected. Because the Fund bears the fees and expenses of the underlying funds in which it invests, a reallocation of the Fund's investments to underlying funds with higher fees or expenses will increase the Fund's total expenses. The fees and expenses associated with an investment in the Fund are less predictable than those associated with an investment in funds that charge a fixed management fee.
Large Shareholder Risk. To the extent a large number of shares of the Fund is held by a single shareholder (e.g., institutional investors), the Fund is subject to the risk that a redemption by that shareholder of all or a large portion of its shares will disrupt the Fund's operations.
Leveraging Risk. The use of reverse repurchase agreements and other derivatives and securities lending creates leverage. Leverage increases the Fund's losses when the value of its investments (including derivatives) declines.
Liquidity Risk. Low trading volume, lack of a market maker, large position size, or legal restrictions may limit or prevent the Fund or an underlying fund from selling particular securities or unwinding derivative positions at desirable prices.
Management and Operational Risk. Benchmark-Free Allocation Fund and the underlying funds run the risk that GMO's investment techniques will fail to produce desired results (including the annualized excess returns Benchmark-Free Allocation seeks above the Consumer Price Index). Benchmark-Free Allocation Fund's and the underlying funds' portfolio managers may use quantitative analyses and models, and any imperfections, errors, or limitations in those analyses and models could affect the ability of the portfolio managers to implement such fund's strategies. By necessity, these analyses and models make simplifying assumptions that limit their efficacy. Models that appear to explain prior market data can fail to predict future market events. Further, the data used in models may be inaccurate and may not include the most recent information about a company or a security. The Fund also runs the risk that GMO's assessment of an investment may be wrong or that deficiencies in GMO's or another service provider's internal systems or controls will cause losses or impair operations for Benchmark-Free Allocation Fund or the underlying funds.
Market Disruption and Geopolitical Risk. Geopolitical and other events may disrupt securities markets and adversely affect global economies and markets. Those events as well as other changes in foreign and domestic economic and political conditions, could adversely affect the value of the Fund's investments.
Market Risk - Asset-Backed Securities. The market price of fixed income investments with complex structures, such as asset backed securities, can decline due to a number of factors, including market uncertainty about their credit quality and the reliability of their payment streams. Payment streams associated with asset-backed securities held by the Fund depend on many factors (e.g., the cash flow generated by the assets backing the securities, the deal structure, the credit worthiness of any credit-support provider, and the reliability of various other service providers with access to the payment stream), and a problem in any one of these areas can lead to a reduction in the payment stream GMO expected the Fund to receive at the time the Fund purchased the asset-backed security.
Market Risk - Equities. The market prices of equities may decline due to factors affecting the issuing companies, their industries, or the economy and equity markets generally. If an underlying fund purchases equities at a discount from their value as determined by GMO, the Benchmark-Free Allocation Fund runs the risk that the market prices of these investments will not appreciate or will decline for a variety of reasons, one of which may be GMO's overestimation of the value of those investments. An underlying fund also may purchase equities that typically trade at higher multiples of current earnings than other securities, and the market prices of these investments often are more sensitive to changes in future earnings expectations than the market prices of equities trading at lower multiples. In addition, the value of the Fund's shares will be adversely affected if the equities that are subject of the underlying fund's short position appreciate in value.
Market Risk - Fixed Income Investments. The market price of a fixed income investment can decline due to a number of market-related factors, including rising interest rates and widening credit spreads, or decreased liquidity stemming from the market's uncertainty about the value of a fixed income investment (or class of fixed income investments).
Natural Resources Risk. To the extent an underlying fund concentrates its assets in the natural resources sector, the value of its portfolio is subject to factors affecting the natural resources industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries.
Non-Diversified Funds Risk. The Fund invests a portion of its assets in shares of one or more other funds that are not "diversified" investment companies within the meaning of the Investment Company Act of 1940 (the "1940 Act"). This means they are allowed to invest in the securities of a relatively small number of issuers and/or non-U.S. currencies. As a result, they may be subject to greater credit, market and other risks, and poor performance by a single issuer may have a greater impact on their performance, than if they were "diversified." The Fund may invest without limitation in funds that are not diversified.
Options Risk. The market price of options written by an underlying fund will be affected by many factors, including changes in the market price or dividend rates of underlying securities (or in the case of indices, the securities comprising such indices); changes in interest rates or exchange rates; changes in the actual or perceived volatility of the relevant stock market and underlying securities; and the time remaining before an option's expiration.
Short Sales Risk. The Fund runs the risk that an underlying fund's loss on a short sales of securities that the underlying Fund does not own is unlimited.
Smaller Company Risk. Smaller companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, or may lack managers with experience or depend on a few key employees. The securities of small- and mid-cap companies often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalization.
Real Estate Risk. To the extent an underlying fund concentrates its assets in real estate-related investments, the value of its portfolio is subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries.

Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
The Fund is a diversified investment that invests substantially all of its investable assets in the GMO Benchmark-Free Allocation Fund (the "Benchmark-Free Allocation Fund"), an investment company managed by Grantham, Mayo, Van Otterloo & Co. LLC ("GMO"). GMO seeks to achieve Benchmark-Free Allocation Fund's investment objective by investing in asset classes that GMO believes offer the most attractive return and risk opportunities. The asset classes include:
-
U.S. and foreign equity, including emerging markets;
-
U.S. and foreign fixed income, including emerging markets; and
-
alternative asset classes, including real estate and commodities.
GMO uses multi-year forecasts of returns and risk for asset classes to determine Benchmark-Free Allocation Fund's allocations. The factors considered and investment methods used by GMO can change over time.
Benchmark-Free Allocation Fund is structured as a fund of funds and gains its investment exposures primarily by investing in the GMO Implementation Fund. In addition, Benchmark-Free Allocation Fund may invest in other GMO Funds (together with GMO Implementation Fund, the "underlying funds"), principally GMO Alpha Only Fund, GMO Debt Opportunities Fund, GMO Alternative Asset Opportunity Fund, GMO Emerging Country Debt Fund, and GMO Flexible Equities Fund. GMO Implementation Fund is permitted to invest in any asset class. Benchmark-Free Allocation Fund also may invest in securities or derivatives directly.
Benchmark-Free Allocation Fund seeks annualized excess returns of 5% (net of Benchmark-Free Allocation Fund fees) above the Consumer Price Index, with annualized volatility of 5-10%, over a complete market cycle. GMO does not manage Benchmark-Free Allocation Fund to, or control Benchmark-Free Allocation Fund's risk relative to, any securities index or securities benchmark.
Benchmark-Free Allocation Fund is permitted to invest (through GMO Implementation Fund, another underlying fund or directly) in any asset class, country, or sector and at times may have substantial exposure to a single asset class, country, or sector. In addition, Benchmark-Free Allocation Fund is not restricted in its exposure to any particular market and may invest in securities of companies of any market capitalization. Benchmark-Free Allocation Fund may have indirect exposure to derivatives and short sales through its investment in GMO Implementation Fund and other underlying funds. GMO's ability to shift investments within GMO Implementation Fund and between it and other underlying funds is not subject to any limits.
Benchmark-Free Allocation Fund also may invest in GMO U.S. Treasury Fund and unaffiliated money market funds.
While the Fund invests substantially all of its investable assets in the Benchmark-Free Allocation Fund, the Fund may hold cash for short periods of time in order to mitigate the expenses associated with the purchase and sale of shares of the Benchmark-Free Allocation Fund.

Principal Investment Risks
|
|
Risk Narrative [Text Block] |
rr_RiskNarrativeTextBlock |
Because the Fund invests substantially all of its investable assets in Benchmark-Free Allocation Fund, which, in turn, invests all of its assets in a number of underlying funds, the following principal risks are those risks that result from the Fund's indirect investments in the underlying funds or direct investment in Benchmark-Free Allocation Fund. In this section, references to the Fund should be read to include the Fund, Benchmark-Free Allocation Fund and the underlying funds, as appropriate.
The Fund's performance will not correlate perfectly with that of Benchmark-Free Allocation Fund due to the impact of the Fund's fees and expenses and to the timing and magnitude of cash flows into and out of the Fund which will create cash balances that cause the Fund's performance to deviate from the performance of the Benchmark-Free Allocation Fund.
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.
Commodities Risk. Commodities prices can be extremely volatile and exposure to commodities can cause the net asset value of the Fund's shares to decline and fluctuate in a rapid and unpredictable manner.
Counterparty Risk. The Fund runs the risk that the counterparty to a derivatives contract, a clearing member used by the Fund to hold a cleared derivatives contract, or a borrower of the Fund's securities will be unable or unwilling to make timely settlement payments, return the Fund's margin or otherwise honor its obligations.
Credit Risk. The Fund runs the risk that the issuer or guarantor of a fixed income investment or the obligor of an obligation underlying an asset-backed security will be unable or unwilling to satisfy its obligations to pay principal and interest or otherwise to honor its obligations in a timely manner. The market price of a fixed income investment will normally decline as a result of the issuer's, guarantor's, or obligor's failure to meet its payment obligations. Below investment grade securities (also known as "junk bonds") have speculative characteristics, and changes in economic conditions or other circumstances are more likely to impair the capacity of issuers to make principal and interest payments than is the case with issuers of investment grade securities.
Currency Risk. Fluctuations in exchange rates can adversely affect the market value of foreign currency holdings and investments denominated in foreign currencies. In addition, hedging a foreign currency can have a negative effect on performance if the U.S. dollar declines in value relative to that currency.
Derivatives Risk. The use of derivatives involves the risk that their value may not move as expected relative to the value of the underlying assets, rates or indices. Derivatives also present other risks, including market risk, liquidity risk, currency risk and counterparty risk.
Focused Investment Risk. Focusing investments in countries, regions, sectors or companies or in industries with high positive correlations to one another creates more risk than if the Fund's investments were less correlated.
Foreign Investment Risk. The market prices of many foreign securities fluctuate more than those of U.S. securities. Many foreign markets are less stable, smaller, less liquid and less regulated than U.S. markets, and the cost of trading in those markets often is higher than in U.S. markets. Foreign portfolio transactions generally involve higher commission rates, transfer taxes and custodial costs than similar transactions in the U.S. In addition, the Fund may be subject to foreign taxes on capital gains or other income payable on foreign investments, on transactions in those investments and on the repatriation of proceeds generated from those investments. Also, many foreign markets require a license for the fund to invest directly in those markets, and the fund is subject to the risk that it could not invest if its license were terminated or suspended. In some foreign markets, prevailing custody and trade settlement practices (e.g., the requirement to pay for securities prior to receipt) expose the Fund to credit and other risks with respect to participating brokers, custodians, clearing banks or other clearing agents, escrow agents and issuers. Further, adverse changes in investment regulations, capital requirements or exchange controls could adversely affect the value of the Fund's investments. These and other risks (e.g., nationalization, expropriation or other confiscation of assets of foreign issuers) tend to be greater for investments in companies tied economically to emerging countries, the economies ofwhich tend to be more volatile than the economies of developed countries.
Fund of Funds Risk. The Fund is indirectly exposed to all of the risks of an investment in the underlying funds in which it invests, including the risk that those underlying funds will not perform as expected. Because the Fund bears the fees and expenses of the underlying funds in which it invests, a reallocation of the Fund's investments to underlying funds with higher fees or expenses will increase the Fund's total expenses. The fees and expenses associated with an investment in the Fund are less predictable than those associated with an investment in funds that charge a fixed management fee.
Large Shareholder Risk. To the extent a large number of shares of the Fund is held by a single shareholder (e.g., institutional investors), the Fund is subject to the risk that a redemption by that shareholder of all or a large portion of its shares will disrupt the Fund's operations.
Leveraging Risk. The use of reverse repurchase agreements and other derivatives and securities lending creates leverage. Leverage increases the Fund's losses when the value of its investments (including derivatives) declines.
Liquidity Risk. Low trading volume, lack of a market maker, large position size, or legal restrictions may limit or prevent the Fund or an underlying fund from selling particular securities or unwinding derivative positions at desirable prices.
Management and Operational Risk. Benchmark-Free Allocation Fund and the underlying funds run the risk that GMO's investment techniques will fail to produce desired results (including the annualized excess returns Benchmark-Free Allocation seeks above the Consumer Price Index). Benchmark-Free Allocation Fund's and the underlying funds' portfolio managers may use quantitative analyses and models, and any imperfections, errors, or limitations in those analyses and models could affect the ability of the portfolio managers to implement such fund's strategies. By necessity, these analyses and models make simplifying assumptions that limit their efficacy. Models that appear to explain prior market data can fail to predict future market events. Further, the data used in models may be inaccurate and may not include the most recent information about a company or a security. The Fund also runs the risk that GMO's assessment of an investment may be wrong or that deficiencies in GMO's or another service provider's internal systems or controls will cause losses or impair operations for Benchmark-Free Allocation Fund or the underlying funds.
Market Disruption and Geopolitical Risk. Geopolitical and other events may disrupt securities markets and adversely affect global economies and markets. Those events as well as other changes in foreign and domestic economic and political conditions, could adversely affect the value of the Fund's investments.
Market Risk - Asset-Backed Securities. The market price of fixed income investments with complex structures, such as asset backed securities, can decline due to a number of factors, including market uncertainty about their credit quality and the reliability of their payment streams. Payment streams associated with asset-backed securities held by the Fund depend on many factors (e.g., the cash flow generated by the assets backing the securities, the deal structure, the credit worthiness of any credit-support provider, and the reliability of various other service providers with access to the payment stream), and a problem in any one of these areas can lead to a reduction in the payment stream GMO expected the Fund to receive at the time the Fund purchased the asset-backed security.
Market Risk - Equities. The market prices of equities may decline due to factors affecting the issuing companies, their industries, or the economy and equity markets generally. If an underlying fund purchases equities at a discount from their value as determined by GMO, the Benchmark-Free Allocation Fund runs the risk that the market prices of these investments will not appreciate or will decline for a variety of reasons, one of which may be GMO's overestimation of the value of those investments. An underlying fund also may purchase equities that typically trade at higher multiples of current earnings than other securities, and the market prices of these investments often are more sensitive to changes in future earnings expectations than the market prices of equities trading at lower multiples. In addition, the value of the Fund's shares will be adversely affected if the equities that are subject of the underlying fund's short position appreciate in value.
Market Risk - Fixed Income Investments. The market price of a fixed income investment can decline due to a number of market-related factors, including rising interest rates and widening credit spreads, or decreased liquidity stemming from the market's uncertainty about the value of a fixed income investment (or class of fixed income investments).
Natural Resources Risk. To the extent an underlying fund concentrates its assets in the natural resources sector, the value of its portfolio is subject to factors affecting the natural resources industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries.
Non-Diversified Funds Risk. The Fund invests a portion of its assets in shares of one or more other funds that are not "diversified" investment companies within the meaning of the Investment Company Act of 1940 (the "1940 Act"). This means they are allowed to invest in the securities of a relatively small number of issuers and/or non-U.S. currencies. As a result, they may be subject to greater credit, market and other risks, and poor performance by a single issuer may have a greater impact on their performance, than if they were "diversified." The Fund may invest without limitation in funds that are not diversified.
Options Risk. The market price of options written by an underlying fund will be affected by many factors, including changes in the market price or dividend rates of underlying securities (or in the case of indices, the securities comprising such indices); changes in interest rates or exchange rates; changes in the actual or perceived volatility of the relevant stock market and underlying securities; and the time remaining before an option's expiration.
Short Sales Risk. The Fund runs the risk that an underlying fund's loss on a short sales of securities that the underlying Fund does not own is unlimited.
Smaller Company Risk. Smaller companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, or may lack managers with experience or depend on a few key employees. The securities of small- and mid-cap companies often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalization.
Real Estate Risk. To the extent an underlying fund concentrates its assets in real estate-related investments, the value of its portfolio is subject to factors affecting the real estate industry and may fluctuate more than the value of a portfolio that consists of securities of companies in a broader range of industries.
