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. 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 59% of the average value of its portfolio.

The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests primarily in (1) domestic and foreign corporate debt securities; (2) U.S. Government securities, including U.S. Government agency mortgage-backed securities; (3) securities issued by foreign governments, their agencies or instrumentalities, and (4) up to 35% of net assets in lower-grade (high yield) debt securities, i.e., “junk bonds,” of U.S. and foreign companies. The Fund’s assets will normally be invested in each of these four sectors, however the Fund may invest up to 100% of its total assets in U.S. Government securities. The Fund may invest up to 50% of its total assets in foreign securities and up to 15% of its total assets in securities of issuers located in developing markets. Developing countries are those countries that are in the initial stages of their industrial cycles. The Fund may invest up to 25% of its total assets in government securities of any one foreign country. The Fund may also invest up to 10% of its total assets in equity securities of U.S. and foreign issuers. The Fund may invest in debt obligations issued by certain supranational entities, such as the World Bank. The Fund can invest in derivative instruments, specifically credit default swaps and credit default swap indices, interest rate swaps, interest rate futures and forward foreign currency contracts. A credit default swap is an agreement between two parties where the first party agrees to make one or more payments to the second party, while the second party assumes the risk of certain defaults. The Fund can enter into credit default swaps to create long or short exposure to corporate or sovereign debt securities. The Fund can buy a credit default swap (buy credit protection) or sell a credit default swap (sell credit protection). When the Fund buys a credit default swap it makes a stream of payments based on a fixed interest rate (the premium) over the life of the swap in exchange for a counterparty (the seller) taking on the risk of default of a reference debt obligation. Alternatively, the Fund can sell a credit default swap whereby the Fund will receive premium payments from the buyer in exchange for taking the risk of default of the underlying reference obligation. The Fund can invest in credit default swap indices which are credit derivatives used to hedge credit risk or take a position on a basket of credit entities. Credit default swap indices allow an investor to gain or reduce exposure on a basket of credit entities in a more efficient manner than transacting in single name credit default swaps. Unlike a credit default swap, a credit default swap index is a standardized credit security and therefore may be more liquid. The Fund can invest in interest rate swaps and interest rate futures to hedge its exposure to interest rates. An interest rate swap is an agreement between two parties pursuant to which the parties exchange a floating interest rate payment for a fixed interest rate payment based on a specified principal or notional amount. An interest rate futures contract is an exchange-traded contact in which the specified underlying security is either an interest-bearing fixed income security or an inter-bank deposit. Interest rate futures are based off an underlying security which is a debt obligation and moves in value as interest rates change. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to gain or modify exposure to a particular currency. The Fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers then decide on risk factors to use in managing the Fund relative to that benchmark. In doing so, the portfolio managers consider recommendations from a team of independent specialists in positioning the Fund to generate alpha (specific factors affecting the return on investments in excess of the benchmark). The portfolio managers generally rely upon a different team of specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. The portfolio managers rely on the specialists for adjusting the Fund’s risk exposures and security selection. Decisions to purchase or sell securities are determined by the relative value considerations of the investment professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund’s macro risk exposure (e.g. duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund’s exposure to a particular security or issuer, degradation of an issuer’s credit quality, or general liquidity needs of the Fund.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating. Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors. Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries. Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. High Yield Bond (Junk Bond) Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time. Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. Mortgage- and Asset-Backed Securities Risk. The Fund may invest in mortgage- and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower’s payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund’s income. Conversely, when interest rates rise, prepayments may happen more slowly, causing the security to lengthen in duration. Longer duration securities tend to be more volatile. Securities may be prepaid at a price less than the original purchase value. An unexpectedly high rate of defaults on the mortgages held by a mortgage pool may adversely affect the value of mortgage-backed securities and could result in losses to the Fund. The risk of such defaults is generally higher in the case of mortgage pools that include subprime mortgages. Subprime mortgages refer to loans made to borrowers with weakened credit histories or with lower capacity to make timely payments on their mortgages. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default.
