Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 26.41% of the average value of its portfolio.

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 securities of any maturity, such as bonds, notes, bills and debentures.

The Fund invests predominantly in bonds issued by governments and government agencies located around the world, including inflation-indexed securities. In addition, the Fund’s assets will be invested in issuers located in at least three countries (including the U.S.).

Although the Fund may buy bonds rated in any category, it focuses on "investment grade" bonds. These are issues rated in the top four rating categories by independent rating agencies 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 comparable. The Fund may invest up to 25% of its total assets in bonds that are rated below investment grade. Generally, lower rated securities pay higher yields than more highly rated securities to compensate investors for the higher risk. The Fund may invest without limit in developing markets. 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 goals, the Fund regularly uses various currency related transactions involving derivative instruments, principally currency and cross currency forwards, but may also use 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 the instruments. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies.

The investment manager allocates the Fund's assets based upon its assessment of changing market, political and economic conditions. It will consider various factors, including evaluation of interest and currency exchange rate changes and credit 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.

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.

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 typically are greater in less developed countries or emerging market countries.

Developing Market Countries

The Fund’s investments in developing 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.

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.

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.

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. 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.

Derivative Instruments

The performance of derivative instruments (including currency related derivatives) depends largely on the performance of an underlying currency, security or index and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as enable gains) on an amount that exceeds the Fund's initial investment. Other risks include illiquidity in the Fund, mispricing or improper valuation, 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.

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.

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.

Market

The market values of securities owned by the Fund will go up and 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.

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.

Historical performance for Class R shares prior to its inception is based on the performance of Class A shares. Class R performance has been adjusted to reflect differences in sales charges and 12b-1 expenses between classes.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

Under normal market conditions, the Fund invests primarily in fixed and floating rate debt securities and debt obligations (including convertible bonds) of governments, government-related or corporate issuers worldwide (collectively, “bonds”). Bonds include debt securities of any maturity, such as bonds, notes, bills and debentures. The Fund may also invest in inflation-indexed securities and securities or structured products that are linked to or derive their value from another security, asset or currency of any nation. In addition, the Fund's assets will be invested in issuers located in at least three countries (including the U.S.). The Fund may invest a substantial portion of its assets in developing markets.

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.

The Fund may buy bonds rated in any category, including securities in default. The Fund may invest in debt securities of any maturity, and the average maturity of debt securities in the Fund’s portfolio will fluctuate depending on the investment manager’s outlook on changing market, economic, and political conditions.

For purposes of pursuing its investment goals, the Fund regularly uses various currency related transactions involving derivative instruments, principally currency and cross currency forwards, but may also use currency and currency index futures contracts.

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.

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.

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 typically are greater in less developed countries or emerging market countries.

Developing Market Countries

The Fund’s investments in developing 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.

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. 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.

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.

Derivative Instruments

The performance of derivative instruments (including currency related derivatives) depends largely on the performance of an underlying currency, security or index and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as enable gains) on an amount that exceeds the Fund's initial investment.

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.

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.

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.

Market

The market values of securities owned by the Fund will go up and 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.

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.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 16.91% of the average value of its portfolio.

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 securities of any maturity, such as bonds, notes, bills and debentures.

The Fund invests predominantly in bonds issued by governments and government agencies located outside the U.S. including inflation-indexed securities.

Although the Fund may buy bonds rated in any category, it focuses on "investment grade" bonds. These are issues rated in the top four rating categories by independent rating agencies 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 comparable. The Fund may invest up to 35% of its total assets in bonds that are rated below investment grade. Generally, lower rated securities pay higher yields than more highly rated securities to compensate investors for the higher risk. The Fund may invest without limit in developing markets. 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 goals, the Fund regularly uses various currency related transactions involving derivative instruments, principally currency and cross currency forwards, but may also use 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 the instruments. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies.

The investment manager allocates the Fund's assets based upon its assessment of changing market, political and economic conditions. It will consider various factors, including evaluation of interest and currency exchange rate changes and credit risks.

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.

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.

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 typically are greater in less developed countries or emerging market countries.

Developing Market Countries

The Fund’s investments in developing 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.

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.

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.

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. 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.

Derivative Instruments

The performance of derivative instruments (including currency related derivatives) depends largely on the performance of an underlying currency, security or index and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as enable gains) on an amount that exceeds the Fund's initial investment. Other risks include illiquidity in the Fund, mispricing or improper valuation, 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.

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.

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.

Market

The market values of securities owned by the Fund will go up and 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.
