| 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 its most recent fiscal year, the fund’s portfolio turnover rate was 37% of the average value of its portfolio. | ||

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be: | ||
| Strategy [Heading] | rr_StrategyHeading | <span style="color:#000000;font-family:Arial Narrow;font-size:10pt;font-weight:bold;">Principal investment strategies</span> | ||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal market conditions, the fund invests at least 80% of its assets in the following types of securities, which may be denominated in U.S. dollars or foreign currencies: foreign government and corporate debt securities from developed and emerging markets, U.S. government and agency securities, domestic high-yield bonds, and investment-grade corporate bonds and currency instruments. The fund may also invest in preferred stock and other types of debt securities, including mortgage-and asset-backed securities and loans. Direct investments in loans may be illiquid and holding a loan could expose the fund to the risk of being a direct lender. No more than 80% of the fund’s assets will consist of instruments denominated in foreign currencies. Although the fund may invest up to 10% of its total assets in securities rated as low as D (in default) by S&P Global Ratings (S&P) or Moody’s Investors Service, Inc. (Moody’s), or their unrated equivalents, it generally intends to keep its average credit quality in the investment-grade range (i.e., AAA to BBB). Bonds that are rated at or below BB by S&P or Ba by Moody’s are considered junk bonds. There is no limit on the average maturity of the fund’s portfolio. The fund’s investment policies are based on credit ratings at the time of purchase. Under normal circumstances, the fund may invest up to 15% of total assets in asset-backed securities rated lower than A by S&P or Moody’s, or their unrated equivalents (but under no circumstances lower than B or their unrated equivalents). In managing the fund, the manager allocates assets among the four major types of instruments noted above based on analysis of global economic factors such as fiscal and monetary policies, projected international interest-rate movements, political environments, and currency trends. In abnormal circumstances, the manager may invest up to 100% of the fund’s assets in any one sector. The manager looks for investments that are appropriate for the fund in terms of yield, credit quality, structure, and industry distribution. Relative yields and risk/reward ratios are the primary considerations in selecting securities. The fund may use certain higher-risk investments, including derivatives such as futures, options, and swaps (including credit default swaps), as well as restricted or illiquid securities. The fund may also invest significantly in currency spots and forwards, currency futures and options, and interest-rate options for both hedging and nonhedging purposes, including for purposes of enhancing returns. In addition, the fund may invest up to 10% of its net assets in domestic or foreign common stocks. The manager considers environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund’s investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. The fund may trade securities actively and its investment process may, at times, result in a higher-than-average portfolio turnover ratio. | ||

| Class NAV | Strategic Income Opportunities Fund | Risk Not Insured Depository Institution [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||
| Class NAV | Strategic Income Opportunities Fund | Changing Distribution Levels Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Changing distribution levels risk. The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines. | ||
| Class NAV | Strategic Income Opportunities Fund | Credit And Counterparty Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Credit and counterparty risk. The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund’s securities could affect the fund’s performance. | ||
| Class NAV | Strategic Income Opportunities Fund | Currency Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Currency risk. Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund’s investments. Foreign currencies may decline in value, which could negatively impact performance. | ||
| Class NAV | Strategic Income Opportunities Fund | Defaulted Debt Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Defaulted debt risk. Investing in defaulted debt securities is speculative and involves substantial risks in addition to those of non-defaulted high-yield securities. Defaulted debt securities generally do not generate interest payments. Principal on defaulted debt might not be repaid, and a fund could lose up to its entire investment. | ||
| Class NAV | Strategic Income Opportunities Fund | Economic And Market Events Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate. | ||
| Class NAV | Strategic Income Opportunities Fund | Equity Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Equity securities risk. The price of equity securities may decline due to changes in a company’s financial condition or overall market conditions. | ||
| Class NAV | Strategic Income Opportunities Fund | ESG Integration Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | ESG integration risk. The manager considers ESG factors that it deems relevant or additive, along with other material factors and analysis, when managing the fund. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The manager may consider these ESG factors on all or a meaningful portion of the fund’s investments. Incorporating ESG criteria and making investment decisions based on certain ESG characteristics, as determined by the manager, carries the risk that the fund may perform differently, including underperforming, funds that do not utilize ESG criteria, or funds that utilize different ESG criteria. | ||
| Class NAV | Strategic Income Opportunities Fund | Fixed Income Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security’s credit quality may adversely affect fund performance. | ||
| Class NAV | Strategic Income Opportunities Fund | Foreign Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Foreign securities risk. Less information may be publicly available regarding foreign issuers, including foreign government issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. | ||
| Class NAV | Strategic Income Opportunities Fund | Hong Kong Bond Connect Program (Bond Connect) risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Hong Kong Bond Connect Program (Bond Connect) risk. Trading in China bonds through Bond Connect, a mutual market access program that enables foreign investment in the People’s Republic of China (PRC), is subject to certain restrictions and risks. Bonds listed on Bond Connect may lose purchase eligibility, which could adversely affect the fund’s performance. Trading through Bond Connect is subject to trading, clearance, and settlement procedures that may continue to develop as the program matures. Any changes in laws, regulations and policies applicable to Bond Connect may affect bond prices. These risks are heightened by the underdeveloped state of the PRC’s investment and banking systems in general. | ||
| Class NAV | Strategic Income Opportunities Fund | Hong Kong Stock Connect Program (Stock Connect) Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Hong Kong Stock Connect Program (Stock Connect) risk. Trading in China A-Shares through Stock Connect, a mutual market access program that enables foreign investment in the People’s Republic of China (PRC), is subject to certain restrictions and risks. Securities listed on Stock Connect may lose purchase eligibility, which could adversely affect the fund’s performance. Trading through Stock Connect is subject to trading, clearance, and settlement procedures that may continue to develop as the program matures. Any changes in laws, regulations and policies applicable to Stock Connect may affect China A-Share prices. These risks are heightened by the underdeveloped state of the PRC’s investment and banking systems in general. | ||
| Class NAV | Strategic Income Opportunities Fund | Hedging Derivatives And Other Strategic Transactions Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund’s volatility and could produce disproportionate losses, potentially more than the fund’s principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize include: credit default swaps, foreign currency forward contracts, futures contracts, options and swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk. | ||
| Class NAV | Strategic Income Opportunities Fund | High Portfolio Turnover Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | High portfolio turnover risk. Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions. | ||
| Class NAV | Strategic Income Opportunities Fund | Illiquid And Restricted Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Illiquid and restricted securities risk. Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security’s market price and the fund’s ability to sell the security. | ||
| Class NAV | Strategic Income Opportunities Fund | Liquidity Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets. | ||
| Class NAV | Strategic Income Opportunities Fund | Lower Rated And High Yield Fixed Income Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell. | ||
| Class NAV | Strategic Income Opportunities Fund | Mortgage Backed And Asset Backed Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Mortgage-backed and asset-backed securities risk. Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks. Factors that impact the value of these securities include interest rate changes, the reliability of available information, credit quality or enhancement, and market perception. | ||
| Class NAV | Strategic Income Opportunities Fund | Operational And Cybersecurity Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund’s securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes. | ||
| Class NAV | Strategic Income Opportunities Fund | Preferred And Convertible Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Preferred and convertible securities risk. Preferred stock dividends are payable only if declared by the issuer’s board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock’s value can depend heavily upon the underlying common stock’s value. | ||
| Class NAV | Strategic Income Opportunities Fund | Sector Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Sector risk. When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. | ||
| Class NAV | Strategic Income Opportunities Fund | US Government Agency Obligations Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | U.S. government agency obligations risk. The fund invests in obligations issued by agencies and instrumentalities of the U.S. government. Government-sponsored entities such as Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal Home Loan Banks, although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt securities that they issue are neither guaranteed nor issued by the U.S. government. Such debt securities are subject to the risk of default on the payment of interest and/or principal, similar to the debt securities of private issuers. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. Although the U.S. government has provided financial support to Fannie Mae and Freddie Mac in the past, there can be no assurance that it will support these or other government-sponsored entities in the future. | ||
| Class NAV | Strategic Income Opportunities Fund | US Treasury Obligations Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | U.S. Treasury obligations risk. The market value of direct obligations of the U.S. Treasury may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the fund’s investments in obligations issued by the U.S. Treasury to decline. | ||
