Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

Small Cap 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 Small Cap Fund’s performance.  During the most recent fiscal year, Small Cap Fund’s portfolio turnover rate was 54 percent of the average value of its portfolio.

Expense Example [Heading] rr_ExpenseExampleHeading

Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in Small Cap Fund with the cost of investing in other mutual funds.  The Example assumes that you invest $10,000 in Small Cap Fund for the time periods indicated and then redeem all of your shares at the end of those periods.  The Example also assumes that your investment has a 5 percent return each year and that Small Cap Fund’s operating expenses remain the same as set forth in the table above.  Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Small Cap Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in equity securities of small-cap companies.  Small Cap Fund considers a small-cap company to be a company having at time of purchase a market capitalization of an issuer in the Russell 2000® Index (at the time of the index’s most recent rebalancing, stocks with capitalizations of approximately $100 million to $3 billion).

 

The sub-adviser to Small Cap Fund utilizes a series of well-defined, established processes in order to select and reevaluate securities in the growth and value categories.  The sub-adviser begins with a universe of securities.  Each security in that universe is then evaluated using a series of proprietary screens involving fundamental, quantitative, qualitative and technical analysis.  Once a security has been subjected to those analytical filters, the sub-adviser performs a detailed assessment; develops an investment thesis; sets a price target and initiates a portfolio position.  From time to time, holdings may be diversified by company and industry, although Small Cap Fund is not obligated to remain diversified.  While most assets are typically invested in U.S. common stocks, Small Cap Fund may invest in American Depositary Receipts, or ADRs, and other foreign stocks traded on U.S. exchanges in keeping with Small Cap Fund’s objectives.

 

The sub-adviser generally considers growth stocks to be equity securities issued by companies that have sustainable competitive advantages and products or services that potentially could generate significantly greater-than-average revenue and earnings growth.  The sub-adviser generally considers value stocks to be equity securities issued by companies that have underappreciated but stable earnings and cash flow and where there are visible and imminent inflection points and catalysts that will result in increased earnings and cash flow, driving stock appreciation.

 

Small Cap Fund may lend its securities.  Small Cap Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds.  Small Cap Fund also may take temporary defensive positions that are inconsistent with its principal investment strategies.

Risk [Heading] rr_RiskHeading

Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

It is possible to lose money by investing in Small Cap Fund.  An investment in Small Cap Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

Market, Industry and Specific Holdings.  The share price of Small Cap Fund may fall because of weakness in the stock markets, generally, weaknesses with respect to a particular industry in which Small Cap Fund has significant holdings, or weaknesses associated with one or more specific companies in which Small Cap Fund may have substantial investments.

 

Liquidity Risk.  Small Cap Fund may not be able to sell some or all of its securities at desired prices or may be unable to sell the securities at all.

 

Active Management Risk.  The sub-adviser’s judgments about the attractiveness, value, or potential appreciation of Small Cap Fund’s investments may prove to be incorrect.

 

Small-Capitalization Securities.  Investments in small-capitalization companies typically present greater risks than investments in larger companies and, as a result, the performance of Small Cap Fund may be more volatile than a fund that invests in large-cap stocks.

 

Growth and Value Stock Investing.  Different investment styles periodically come into and fall out of favor with investors. Growth stocks generally are more volatile than the overall stock market.  Value stocks generally carry the risk that the market will not recognize their intrinsic value or that they are actually appropriately priced at a low level.

 

Foreign Investing.  Small Cap Fund’s investments in foreign securities (including ADRs) may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar.

 

Sector. Small Cap Fund currently has significant investments in one or more specific industry sectors, subjecting it to risks greater than general market risk.

 

Non-Diversification.  Small Cap Fund is “non-diversified,” which means that it may invest a higher percentage of its assets in a small number of issuers.  When Small Cap Fund is not diversified, a decline in the value of the securities of one issuer could have a significant negative effect on the value of Small Cap Fund’s portfolio.

 

Securities Lending.  Securities lending involves two primary risks: investment risk and borrower default risk. Investment risk is the risk that Small Cap Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that Small Cap Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

 

Please refer to “Fund Objectives, Strategies and Risks” in the Prospectus for further details.

Strategy [Heading] rr_StrategyHeading

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Quality Fund invests at least 80 percent of its net assets (plus any borrowings for investment purposes) in equity securities of U.S. issuers. Quality Fund principally invests in equity securities of large companies, that is, companies with a market capitalization of greater than $5 billion at time of purchase. However, there is no minimum market capitalization for companies whose securities Quality Fund may purchase.

 

To manage Quality Fund’s portfolio, Quality Fund’s investment manager, in consultation with its sub-adviser, periodically selects what it believes is a well-managed mutual fund (the “target portfolio”) and then purchases and sells Quality Fund assets such that Quality Fund’s portfolio generally holds the same securities and in the same percentages as the target portfolio as of the end of the target portfolio’s most recent fiscal quarter.  If Quality Fund’s assets significantly increase, Quality Fund may select more than one target portfolio.  Among the criteria used to select the target portfolio are the limited availability of the target portfolio to retail investors and the target portfolio’s historical performance.

 

From time to time, a target portfolio may invest in non-U.S. securities.  In such cases, Quality Fund typically invests in American Depositary Receipts (or ADRs), which represent interests in such securities.   Quality Fund also may invest in derivatives, that is, a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments.  Quality Fund also may lend its securities.  Quality Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds.  Quality Fund also may take temporary defensive positions that are inconsistent with its principal investment strategies.

Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

It is possible to lose money by investing in Quality Fund.  An investment in Quality Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

Market, Industry and Specific Holdings.  The share price of Quality Fund may fall because of weakness in the stock markets, generally, weaknesses with respect to a particular industry in which Quality Fund has significant holdings, or weaknesses associated with one or more specific companies in which Quality Fund may have substantial investments.

 

Difficulty in Comparing Fund Performance with Target Portfolio Performance.  Quality Fund performance typically does not mirror the target portfolio’s performance.  Among other things, the holdings of the target portfolio may change significantly during the period between the end of a quarter and the time when those changes are publicly disclosed.  From time to time, Quality Fund may be purchasing specific securities at the same time that the target portfolio is selling them.  In addition, the target portfolio may have lower expenses relative to its assets than Quality Fund.

 

Inability to Conduct Due Diligence on Target Portfolio’s Investment Adviser.  Quality Fund’s investment manager and sub-adviser may be able to perform only limited due diligence on the investment adviser to determine, among other things, whether the investment adviser is adhering to the target portfolio’s investment guidelines and whether the risks disclosed in the target portfolio’s offering documents reflect the risks of the target portfolio.

 

Potential Impact on Target Portfolio.  Quality Fund’s purchases and sales of securities for its own portfolio may adversely impact the management of a target portfolio and thus, Quality Fund itself.

 

Accuracy of Target Portfolio Information.  Any failure by a target portfolio to file accurate and timely portfolio information could affect the performance of Quality Fund.

 

Large- and Mid-Capitalization Securities.  Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by smaller companies.  Larger companies, however, may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

 

Foreign Investing.  Quality Fund’s investments in foreign securities (primarily through ADRs) may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar.

 

Non-Diversification.  Quality Fund is “non-diversified”, which means that it may invest a higher percentage of its assets in a smaller number of issuers.  As a result, a decline in the value of the securities of one issuer could have a significant negative effect on Quality Fund.

 

Sector. Quality Fund may have significant investments in one or more specific industry sectors, subjecting it to risks greater than general market risk.

 

Liquidity Risk.  Quality Fund may not be able to sell some or all of its securities at desired prices or may be unable to sell the securities at all.

 

Securities Lending.  Securities lending involves two primary risks: investment risk and borrower default risk. Investment risk is the risk that Quality Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that Quality Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

 

Derivatives. Quality Fund’s investments in derivative instruments are subject to a number of risks, such as counterparty risk, the risk of mispricing or improper valuation, and the risk that the value of the instrument may not increase or decrease as expected.

Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

Emerging Markets 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 Emerging Markets Fund’s performance.  During the most recent fiscal year, Emerging Markets Fund’s portfolio turnover rate was 25 percent of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Emerging Markets Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in equity securities, including depository receipts, warrants and rights, of emerging markets issuers, that is, an issuer having a country classification assigned by MSCI from a country included in the MSCI Emerging Markets Index (“MSCI EM”).  Emerging Markets Fund generally invests in at least eight countries and three or more broad geographic regions, such as Latin America, Asia or Europe. Emerging Markets Fund may invest greater than 25 percent of its assets in a particular region, but not in a single country in that region. Emerging Markets Fund may invest in companies of any capitalization.

 

To manage Emerging Markets Fund’s assets, the fund allocates its assets between two proprietary strategies: an alpha modeling strategy and a risk-parity strategy.  The alpha modeling strategy integrates a variety of measures including firm-specific, sector-specific and region-specific factors using a quantitative framework to build custom-tailored alpha models for a universe of emerging markets securities. The risk-parity strategy deploys a proprietary portfolio construction process in an attempt to balance risk across the countries, sectors and issuers represented in the MSCI EM.  The sub-adviser seeks to identify the contribution to a portfolio’s risk from exposures to various countries, sectors, and issuers then attempts to balance risk across these dimensions to improve diversification, rather than rely on the securities’ market weights reflected in the MSCI EM.    The Emerging Markets Fund currently invests in Pear Tree PanAgora Risk Parity Emerging Markets Fund to achieve it risk-parity exposure.

 

In addition to emerging markets securities, Emerging Markets Fund also may invest in forward foreign currency exchange contracts as well as other types of derivatives, that is, a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments. Emerging Markets Fund also may lend its securities. Emerging Markets Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds. Emerging Markets Fund also may take temporary defensive positions that are inconsistent with its principal investment strategies.

Risk [Heading] rr_RiskHeading

Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

It is possible to lose money by investing in Emerging Markets Fund. An investment in Emerging Markets Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

Market, Industry and Specific Holdings. The share price of Emerging Markets Fund may fall because of weakness in the stock markets, generally, weaknesses with respect to a particular industry in which Emerging Markets Fund has significant holdings, or weaknesses associated with one or more specific companies in which Emerging Markets Fund may have substantial investments. In addition, to the extent Emerging Markets Fund invests in the risk-parity model, the fund is unlikely to benefit from market momentum preceding a market correction.

 

Foreign Investing. Emerging Markets Fund’s investments in foreign securities (including ADRs) may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar. These risks are especially acute for emerging markets securities.

 

Emerging Markets Risk. The risks of foreign investing are heightened for securities of issuers in emerging market countries. Emerging market countries tend to have economic structures that are less diverse and mature, political systems that are less stable, are more susceptible to governmental interference, and less liquid and efficient trading markets than those of developed countries.

 

Liquidity Risk. Emerging Markets Fund may not be able to sell some or all of its securities at desired prices or may be unable to sell the securities at all.

 

Active Management Risk. The sub-adviser’s judgments about the attractiveness, value, or potential appreciation of Emerging Markets Fund’s investments may prove to be incorrect.

 

Investments in Another Mutual Fund.  To the extent that Emerging Markets Fund invests in another mutual fund, its investment performance would be directly related to the investment performance of the other fund.  It also would indirectly bear its proportionate share of any management and other fees paid by the other mutual fund, subjecting Emerging Markets Fund shareholders to some duplication of fees.

 

Large- and Mid-Capitalization Securities. Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by smaller companies. Larger companies, however, may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

 

Small- and Micro-Capitalization Securities. Investments in small- and micro-capitalization companies typically present greater risks than investments in larger companies and, as a result, 2 the performance of Emerging Markets Fund may be more volatile than a fund that invests only in large- and mid-cap stocks.

 

Growth and Value Stock Investing. Different investment styles periodically come into and fall out of favor with investors. Growth stocks generally are more volatile than the overall stock market. Value stocks generally carry the risk that the market will not recognize their intrinsic value or that they are actually appropriately priced at a low level.

 

Sector. Emerging Markets Fund may have significant investments in one or more specific industry sectors, subjecting it to risks greater than general market risk.

 

Securities Lending. Securities lending involves two primary risks: investment risk and borrower default risk. Investment risk is the risk that Emerging Markets Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that Emerging Markets Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

 

Derivatives. Emerging Markets Fund’s investments in currency futures and other derivative instruments are subject to a number of risks, such as counterparty risk, the risk of mispricing or improper valuation, and the risk that the value of the instrument may not increase or decrease as expected.

Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus

Non-Diversification.  Emerging Markets Fund is “non-diversified,” which means that it may invest a higher percentage of its assets in a smaller number of issuers.  As a result, a decline in the value of the securities of one issuer could have a significant negative effect on Emerging Markets Fund.

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Foreign Value Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in equity securities, warrants, and rights derivative of or convertible into common stocks, in each case issued by foreign markets issuers.  Foreign Value Fund defines a foreign markets issuer to be an issuer that derives at least 50 percent of its gross revenues or profits from goods or services produced in non-U.S. markets or from sales made in non-U.S. markets. Foreign Value Fund generally will be invested in issuers in ten or more foreign countries. Foreign Value Fund may invest in companies of any capitalization.

 

Foreign Value Fund’s sub-adviser uses a three-step investment decision making process, with the objective to identify companies with the most undervalued streams of sustainable cash flow.  First, it employs proprietary quantitative investment technology to evaluate data, such as cash flow and interest rates, to produce a ranking of country and industry sectors.  Second, it uses traditional valuation criteria to regularly screen a database of more than 29,000 companies worldwide to identify a pool of approximately 500 or more securities with the greatest potential for undervalued streams of sustainable cash flow or assets.  Third, the sub-adviser conducts rigorous fundamental research on the pool of companies identified by the first two steps of the investment process. The sub-adviser also maintains a “watch-list” of companies which may be used if the valuation of a company held in Foreign Value Fund’s portfolio falls below established limits.

 

Foreign Value Fund’s sub-adviser may utilize options. The extent of the sub-adviser’s use of options may vary over time based on the sub-adviser’s assessment of market conditions and other factors.  Foreign Value Fund may also buy and sell forward foreign currency exchange contracts in connection with its investments.

 

Foreign Value Fund may invest in other derivatives, that is, a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments.  Foreign Value Fund also may lend its securities.  Foreign Value Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds.  Foreign Value Fund also may take temporary defensive positions that are inconsistent with its principal investment strategies.

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Foreign Value Small Cap Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in equity securities, warrants, and rights derivative of or convertible into common stocks, in each case issued by small cap foreign markets issuers.  Foreign Value Small Cap Fund defines a foreign markets issuer to be an issuer that derives at least 50 percent of its gross revenues or profits from goods or services produced in non-U.S. markets or from sales made in non-U.S. markets.  Foreign Value Small Cap Fund generally will be invested in issuers in ten or more foreign countries.  Foreign Value Small Cap Fund considers a small-cap company to be a company having a market capitalization at time of purchase between $50 million to $2 billion.

 

Foreign Value Small Cap Fund’s sub-adviser uses a three-step investment decision making process, with the objective to identify companies with the most undervalued streams of sustainable cash flow.  First, it employs proprietary quantitative investment technology to evaluate data, such as cash flow and interest rates, to produce a ranking of country and industry sectors.  Second, it uses traditional valuation criteria to regularly screen a database of more than 16,000 companies worldwide to identify a pool of approximately 250 or more securities with the greatest potential for undervalued streams of sustainable cash flow or assets.  Third, the sub-adviser conducts rigorous fundamental research on the pool of companies identified by the first two steps of the investment process. The sub-adviser also maintains a “watch-list” of companies which may be used if the valuation of a company held in Foreign Value Small Cap Fund’s portfolio falls below established limits.

 

Foreign Value Small Cap Fund’s sub-adviser may utilize options. The extent of the sub-adviser’s use of options may vary over time based on the sub-adviser’s assessment of market conditions and other factors.  Foreign Value Small Cap Fund may also buy and sell forward foreign currency exchange contracts in connection with its investments.

 

Foreign Value Small Cap Fund may invest in other derivatives, that is, a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments.  Foreign Value Small Cap Fund also may lend its securities.  Foreign Value Small Cap Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds.  Foreign Value Small Cap Fund also may take temporary defensive positions that are inconsistent with its principal investment strategies.

Risk [Heading] rr_RiskHeading

Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

It is possible to lose money by investing in Foreign Value Small Cap Fund.  An investment in Foreign Value Small Cap Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

Market, Industry and Specific Holdings. The share price of Foreign Value Small Cap Fund may fall because of weakness in the stock markets, generally, weaknesses with respect to a particular industry in which Foreign Value Small Cap Fund has significant holdings, or weaknesses associated with one or more specific companies in which Foreign Value Small Cap Fund may have substantial investments.

 

Foreign Investing.  Foreign Value Small Cap Fund’s investments in foreign securities (including ADRs) may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar.  These risks are especially acute for emerging markets securities.

 

Value Stock Investing.  A value investment style periodically comes into and falls out of favor with investors.  Value stocks generally carry the risk that the market will not recognize their intrinsic value or that they are actually appropriately priced at a low level.

 

Small-Capitalization Securities.  Investments in small-capitalization companies typically present greater risks than investments in larger companies and, as a result, the performance of Foreign Value Small Cap Fund may be more volatile than a fund that invests only in large- and mid-cap stocks.

 

Liquidity Risk.  Foreign Value Small Cap Fund may not be able to sell some or all of its securities at desired prices or may be unable to sell the securities at all.

 

Active Management Risk.  The sub-adviser’s judgments about the attractiveness, value, or potential appreciation of Foreign Value Small Cap Fund’s investments may prove to be incorrect.

 

Non-Diversification.  Foreign Value Small Cap Fund is “non-diversified”, which means that it may invest a higher percentage of its assets in a smaller number of issuers.  As a result, a decline in the value of the securities of one issuer could have a significant negative effect on Foreign Value Small Cap Fund.

 

Sector. Foreign Value Small Cap Fund may have significant investments in one or more specific industry sectors, subjecting it to risks greater than general market risk.

 

Securities Lending.  Securities lending involves two primary risks: investment risk and borrower default risk. Investment risk is the risk that Foreign Value Small Cap Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that Foreign Value Small Cap Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

 

Derivatives. Foreign Value Small Cap Fund’s investments in currency futures, options and other derivative instruments are subject to a number of risks, such as counterparty risk, the risk of mispricing or improper valuation, and the risk that the value of the instrument may not increase or decrease as expected.

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, Risk Parity Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in equity securities, including depository receipts, warrants and rights, of emerging markets issuers, that is, an issuer having a country classification assigned by MSCI from a country included in the MSCI Emerging Markets IndexSM (“MSCI EM”).  Risk Parity Fund generally invests in at least eight countries and three or more broad geographic regions, such as Latin America, Asia or Europe. Risk Parity Fund may invest greater than 25 percent of its assets in a particular region, but not in a single country in that region. Risk Parity Fund may invest in companies of any capitalization.

 

To manage Risk Parity Fund’s assets, its sub-adviser uses its proprietary risk parity strategy.  Its risk parity strategy uses an investment model that assigns a country-, sector-, and issuer-risk value to each security in the MSCI EM, and then builds a portfolio of some of those securities that attempts to balance those risks.  In addition to emerging markets securities, Risk Parity Fund also may invest in forward foreign currency exchange contracts as well as other types of derivatives (that is, a security or instrument whose value is determined by reference to the value or the change in value of one or more securities, currencies, indices or other financial instruments) in order to attempt to mitigate the adverse effects of foreign currency fluctuations. Risk Parity Fund also may lend its securities.  Risk Parity Fund may hold cash, or it may manage its cash by investing in cash equivalents and money market funds.  In unusual market conditions, Risk Parity Fund also may take temporary defensive positions, such as large investments in cash, which are inconsistent with its principal investment strategy.

 Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

 It is possible to lose money by investing in Risk Parity Fund. An investment in Risk Parity Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

 

Market, Industry and Specific Holdings.  The share price of Risk Parity Fund may fall because of weakness in the stock markets, generally, weaknesses with respect to a particular industry in which Risk Parity Fund has significant holdings, or weaknesses associated with one or more specific companies in which Risk Parity Fund may have substantial investments.  In addition, Risk Parity Fund’s strategy, while attempting to limit risks from sudden and substantial market corrections following market “bubbles,” is unlikely to benefit from market momentum preceding a correction.

 

Foreign Investing.  Risk Parity Fund’s investments in foreign securities (including ADRs) may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar. These risks are especially acute for emerging markets securities.

 

Emerging Markets Risk.  The risks of foreign investing are heightened for securities of issuers in emerging market countries. Emerging market countries tend to have economic structures that are less diverse and mature, political systems that are less stable, are more susceptible to governmental interference, and less liquid and efficient trading markets than those of developed countries.

 

Liquidity Risk. Risk Parity Fund may not be able to sell some or all of its securities at desired prices or may be unable to sell the securities at all.

 

Active Management Risk.  The sub-adviser’s judgments about the attractiveness, value, or potential appreciation of Risk Parity Fund’s investments may prove to be incorrect.

 

Large- and Mid-Capitalization Securities.  Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by smaller companies. Larger companies, however, may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

 

Small- and Micro-Capitalization Securities.  Investments in small- and micro-capitalization companies typically present greater risks than investments in larger companies and, as a result, the performance of Risk Parity Fund may be more volatile than a fund that invests only in large- and mid-cap stocks.

 

Growth and Value Stock Investing.  Different investment styles periodically come into and fall out of favor with investors. Growth stocks generally are more volatile than the overall stock market. Value stocks generally carry the risk that the market will not recognize their intrinsic value or that they are actually appropriately priced at a low level.

 

Non-Diversification. Risk Parity Fund is “non-diversified,” which means that it may from time to time invest a higher percentage of its assets in a smaller number of issuers. As a result, a decline in the value of the securities of one issuer could have a significant negative effect on Risk Parity Fund.  It also may be considered more risky for Risk Parity Fund to hold large positions in a single issuer because of the possibility of exercising control over the issuer.

 

Sector. Risk Parity Fund may have significant investments in one or more specific industry sectors, subjecting it to risks greater than general market risk.

 

Securities Lending.  Securities lending involves two primary risks: investment risk and borrower default risk. Investment risk is the risk that Risk Parity Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that Risk Parity Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

 

Derivatives.
