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 51% of the average value of its portfolio. |

Expense Example [Heading] | rr_ExpenseExampleHeading | Example | |||||||||||||
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. 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 those periods or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be: |

Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | |||||||||||||
Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The fund seeks to achieve its objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in high yield securities (“junk bonds”), which are fixed income securities rated below investment grade or unrated and determined to be of similar quality. The fund’s fixed income securities may be fixed-, variable- or floating-rate. The fund invests across the entire range of maturities of high yield securities. The portfolio managers follow a disciplined, fundamental bottom-up research process, which facilitates the early identification of high yield issuers demonstrating an ability to improve their fundamental characteristics. The portfolio managers select issuers that exceed minimum credit statistics and that they believe exhibit high visibility of future expected operating performance. The portfolio managers look for the following in high yield investment candidates: ability to exceed market expectations of operating earnings; the potential for bond rating upgrades; debt reduction capabilities; the ability to secure other sources of capital; and the potential to be recognized as an acquisition candidate. The fundamental research process generally includes: breakdown of a company and its growth by division and region, including revenue model analysis; profit margin analysis; experience and quality of its management; industry dynamics and competitive analysis; distribution channel and supply chain analysis; and macroeconomic climate. The fund may invest in the securities of issuers of any market capitalization, including smaller capitalization companies. The fund may utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time. |

Risk [Heading] | rr_RiskHeading | Principal Risks | |||||||||||||
Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below (in alphabetical order after the first seven risks). > Market Volatility Risk. The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g. Russia’s invasion of Ukraine), acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended. > Issuer Risk. The fund will be affected by factors specific to the issuers of securities and other instruments in which the fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers. > Interest Rate Risk. The values of debt instruments may rise or fall in response to changes in interest rates, and this risk may be enhanced for securities with longer maturities. > High-Yield Fixed Income Securities (Junk Bonds) Risk. High-yield or junk bonds are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to increases in interest rates or an issuer’s deterioration or default. > Counterparty Risk. A counterparty to a derivatives contract, repurchase agreement, a loan of portfolio securities or an unsettled transaction may be unable or unwilling to make timely settlement payments or otherwise honor its obligations to the fund. > Credit Risk. If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline. > Liquidity Risk. Certain securities may be substantially less liquid than many other securities, such as U.S. Government securities or common stocks. To the extent the fund invests in less liquid securities or the level of liquidity in a particular market is constrained, the lack of an active market for investments may cause delay in disposition or force a sale below fair value. > Allocation Risk. If the fund’s exposure to equities and fixed income securities, or to other asset classes, deviates from the intended allocation, or if the fund’s allocation is not optimal for market conditions at a given time, the fund’s performance may suffer. > Debt Instruments Risk. Debt instruments are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s or counterparty’s deterioration or default. > Derivatives Risk. Derivatives may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment. > Focused Investment Risk. To the extent the fund focuses its investments on a limited number of issuers, sectors, industries or geographic regions, it may be subject to increased risk and volatility. > Leverage Risk. When a fund leverages its portfolio by borrowing or certain types of transactions or instruments, including derivatives, fund may be less liquid, may liquidate positions at an unfavorable time, and the volatility of the fund’s value may increase. > Portfolio Turnover Risk. High levels of portfolio turnover increase transaction costs and taxes and may lower investment performance. > Redemption Risk. One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. > Small and Medium Market Capitalization Risk. The fund’s investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies. Please see “More Information About Risks Related to Principal Investment Strategies” in the fund’s prospectus for a more detailed description of the fund’s risks. |
