Foreign Value 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 Foreign Value Fund's performance. During the most recent fiscal year, Foreign Value Fund's portfolio turnover rate was 2 percent of the average value of its portfolio.

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 (i.e., 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) for the purpose of hedging the value of the portfolio or to establish a position in the future. 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.

Principal Investment Risks

Risk, Narrative

rr_RiskNarrativeTextBlock

It is possible to lose money by investing in Foreign Value 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 Foreign Value Fund may fall because of weakness in the stock markets, generally, weaknesses with respect to a particular industry in which Foreign Value Fund has significant holdings, or weaknesses associated with one or more specific companies in which Foreign Value Fund may have substantial investments.

Foreign Investing. Foreign Value 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.

Liquidity Risk. Foreign Value 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 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 Foreign Value Fund may be more volatile than a fund that invests only in large- and mid-cap stocks.

Non-Diversification. Foreign Value 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 Fund.

Sector. Foreign Value 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 Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that Foreign Value Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

Derivatives. Foreign Value 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.
