Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys or 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 transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 94% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	94.00%

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets in fixed-income securities. Under normal market conditions, the Fund invests significantly in fixed-income securities of non-U.S. companies. In addition, the Fund invests, under normal circumstances, in the fixed-income securities of companies located in at least three countries. The Fund may invest in a broad range of fixed-income securities in both developed and emerging markets. The Fund may invest across all fixed-income sectors, including U.S. and non-U.S. Government and corporate debt securities. The Fund's investments may be denominated in local currency or U.S. Dollar-denominated. The Fund may invest in debt securities with a range of maturities from short- to long-term. The Fund may use borrowings or other leverage for investment purposes. The Adviser selects securities for purchase or sale based on its assessment of the securities' risk and return characteristics as well as the securities' impact on the overall risk and return characteristics of the Fund. In making this assessment, the Adviser takes into account various factors, including the credit quality and sensitivity to interest rates of the securities under consideration and of the Fund's other holdings. The Adviser will actively manage the Fund's assets in relation to market conditions and general economic conditions and adjust the Fund's investments in an effort to best enable the Fund to achieve its investment objective. Thus, the percentage of the Fund's assets invested in a particular country or denominated in a particular currency will vary in accordance with the Adviser's assessment of the relative yield and appreciation potential of such securities and the relationship of the country's currency to the U.S. Dollar. Under normal circumstances, the Fund invests at least 75% of its net assets in fixed-income securities rated investment grade at the time of investment and may invest up to 25% of its net assets in below investment grade fixed-income securities (commonly known as "junk bonds"). The Fund may invest in mortgage-related and other asset-backed securities, loan participations, inflation-protected securities, structured securities, variable, floating, and inverse floating rate instruments and preferred stock, and may use other investment techniques. The Fund intends, among other things, to enter into transactions such as reverse repurchase agreements and dollar rolls. The Fund may invest, without limit, in derivatives, such as options, futures, forwards, or swaps.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	MARKET RISK: The value of the Fund's assets will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. INTEREST RATE RISK: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. DURATION RISK: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise. For example, a fixed-income security with a duration of three years will decrease in value by approximately 3% if interest rates increase by 1%. CREDIT RISK: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. BELOW INVESTMENT GRADE SECURITIES: Investments in fixed-income securities with lower ratings (commonly known as "junk bonds") tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the junk bond market generally and less secondary market liquidity. INFLATION RISK: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund's assets can decline as can the value of the Fund's distributions. This risk is significantly greater if the Fund invests a significant portion of its assets in fixed-income securities with longer maturities. FOREIGN (NON-U.S.) RISK: Investments in securities of non-U.S. issuers may involve more risk than those of U.S. issuers. These securities may fluctuate more widely in price and may be less liquid due to adverse market, economic, political, regulatory or other factors. EMERGING MARKET RISK: Investments in emerging market countries may have more risk because the markets are less developed and less liquid as well as being subject to increased economic, political, regulatory or other uncertainties. CURRENCY RISK: Fluctuations in currency exchange rates may negatively affect the value of the Fund's investments or reduce its returns. LEVERAGE RISK: To the extent the Fund uses leveraging techniques, its net asset value, or NAV, may be more volatile because leverage tends to exaggerate the effect of changes in interest rates and any increase or decrease in the value of the Fund's investments. DIVERSIFICATION RISK: The Fund may have more risk because it is "non-diversified", meaning that it can invest more of its assets in a smaller number of issuers and that adverse changes in the value of one security could have a more significant effect on the Fund's NAV. DERIVATIVES RISK: Investments in derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Fund, and may be subject to counterparty risk to a greater degree than more traditional investments. MANAGEMENT RISK: The Fund is subject to management risk because it is an actively managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. As with all investments, you may lose money by investing in the Fund.
