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.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waiver and/or expense reimbursement by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in "bonds." Bonds include debt obligations of any maturity, such as bonds, notes, bills and debentures.

The Fund seeks to achieve its investment goal by investing principally in fixed or floating rate debt securities (including non-investment grade securities, commonly referred to as "junk bonds") and debt obligations issued by government or government-related issuers worldwide. The Fund may also purchase debt obligations issued by supranational entities organized or supported by several national governments, such as the International Bank for Reconstruction and Development or the European Investment Bank. Although the Fund intends to primarily invest in investment grade debt securities, it may also invest up to 15% of its net assets in non-investment grade debt securities. The Fund seeks to manage the portfolio’s exposure to foreign currency, credit, and interest rate risks by investing in both hedged and unhedged, higher and lower credit quality, and varying maturity fixed income securities, as well as cash and cash equivalents.

The Fund may also invest in inflation-indexed securities and securities that are linked to or derive their value from another security, asset or currency of any nation. In addition, the Fund's assets are invested in issuers located in at least three countries (including the U.S.). Under normal market conditions, the Fund expects to invest at least 40% of its net assets in foreign securities. The Fund may invest without limit in emerging markets.

Investment grade bonds are issues rated in the top four rating categories by at least one independent rating agency, such as Standard & Poor’s (S&P®) or Moody’s Investors Service (Moody’s) or, if unrated, determined by the Fund’s investment manager to be of comparable quality. Generally, lower rated securities (also commonly known as “junk bonds”) pay higher yields than more highly rated securities to compensate investors for the higher risk.

The Fund is a "non-diversified" fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund.

For purposes of pursuing its investment goal, the Fund regularly uses various currency related transactions involving derivative instruments, including currency and cross currency forwards and currency and currency index futures contracts. The Fund maintains significant positions in currency related derivative instruments as a hedging technique or to implement a currency investment strategy, which could expose a large amount of the Fund's assets to obligations under these instruments. The Fund may also enter into various other transactions involving derivatives, including interest rate/bond futures and interest rate swap agreements. These derivative instruments may be used for hedging purposes, to enhance returns, or to obtain net long or net negative (short) exposure to selected currencies, interest rates, countries or durations.

The investment manager allocates the Fund's assets based upon its assessment of changing market, political and economic conditions. It considers various factors, including evaluation of interest rates, and currency exchange rate changes and credit risks. The investment manager may consider selling a security when it believes the security has become fully valued due to either its price appreciation or changes in the issuer's fundamentals, or when the investment manager believes another security is a more attractive investment opportunity.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Foreign Securities

Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: political and economic developments - the political, economic and social structures of some foreign countries may be less stable and more volatile than those in the U.S.; trading practices - government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; availability of information - foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; limited markets - the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments may be greater in developing or emerging market countries.

Currency Management Strategies

Currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the investment manager expects. In addition, currency management strategies, to the extent that they reduce the Fund’s exposure to currency risks, may also reduce the Fund’s ability to benefit from favorable changes in currency exchange rates. Using currency management strategies for purposes other than hedging further increases the Fund’s exposure to foreign investment losses. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns.

Emerging Markets

The Fund’s investments in emerging market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Credit

An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.

Sovereign Debt Securities

Sovereign debt securities are subject to various risks in addition to those relating to debt securities and foreign securities generally, including, but not limited to, the risk that a governmental entity may be unwilling or unable to pay interest and repay principal on its sovereign debt, or otherwise meet its obligations when due because of cash flow problems, insufficient foreign reserves, the relative size of the debt service burden to the economy as a whole, the government’s policy towards principal international lenders such as the International Monetary Fund, or the political considerations to which the government may be subject. If a sovereign debtor defaults (or threatens to default) on its sovereign debt obligations, the indebtedness may be restructured. Some sovereign debtors have in the past been able to restructure their debt payments without the approval of some or all debt holders or to declare moratoria on payments. In the event of a default on sovereign debt, the Fund may also have limited legal recourse against the defaulting government entity.

High-Yield Debt Securities

Issuers of lower-rated or "high-yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. High-yield debt instruments are generally considered predominantly speculative by the applicable rating agencies. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

Regional

Adverse conditions in a certain region or country can adversely affect securities of issuers in other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or a particular country, the Fund will generally have more exposure to the specific regional or country economic risks. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region or country where a substantial portion of the Fund's assets are invested, the Fund may experience substantial illiquidity or reduction in the value of the Fund's investments.

Market

The market values of securities owned by the Fund will go up or down, sometimes rapidly or unpredictably. A security’s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Interest Rate

When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these interest rate changes.

Variable rate securities, however, generally will not increase in market value if interest rates decline. Fixed rate debt securities generally are more sensitive to interest rate changes than variable rate securities.

Income

Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.

Derivative Instruments

The performance of derivative instruments depends largely on the performance of an underlying instrument, such as a currency, security or index, and such derivatives often have risks similar to their underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the Fund's portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that exceeds the Fund's initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. When used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.

Inflation-Indexed Securities

Inflation-indexed securities have a tendency to react to changes in real interest rates. Real interest rates represent nominal (stated) interest rates lowered by the anticipated effect of inflation. In general, the price of an inflation-indexed security can decrease when real interest rates increase, and can increase when real interest rates decrease. Interest payments on inflation-indexed securities will fluctuate as the principal and/or interest is adjusted for inflation and can be unpredictable.

Non-Diversification

Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting similar issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Fund’s shares and greater risk of loss.

Management

The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.
